Overview:

U/W Mystic Control (also Stoneblade or Blade Control) is a blue/white aggro-control deck built around Stoneforge Mystic and Jace, the Mind Sculptor. The deck is a direct port of Standard post-New Phyrexia Caw-Blade, which led to the June 2011 banning of both aforementioned cards. Until the bans, Standard Caw-Blade was (according to some sources) by percentage the most dominant deck in Magic tournament history. The Legacy port preserves the same engine but adds many of the best blue (and some white) cards ever printed.

History:

U/W Mystic Control’s debut performance was at Grand Prix Providence 2011, where Team Fireball’s Owen Turtenwald piloted it to an undefeated day 1 and a 5th place overall finish. In the months following, U/W Mystic Control exploded in popularity and success, taking multiple top 8/ top 16 spots at StarCityGames Legacy events in the US and other high-profile tournaments around the world.

Card Choices:

As before, Legacy U/W Mystic Control is a direct port of Standard Caw. They both begin with the same basic engine:

4 Stoneforge Mystic
1 Batterskull

3-4 Jace, the Mind Sculptor

These 8-9 cards give the deck its identity. Prior to New Phyrexia, Stoneforge Mystic was a mid-level value creature seen in various Bant and G/x aggro decks and Jace was considered too slow as more than a two-of, even in Standstill-based control decks. New Phyrexia changed all that in two major ways.

First, the printing of Batterskull gave Mystic a target that needed no extra help once it hit play. It provided a large body, reusability and functioned equally well as both an attacker and defender due to Vigilance and Lifelink. Prior to Batterskull, the consensus best SFM targets were Umezawa’s Jitte and Sword of Fire and Ice. Jitte, while powerful, had the problem of needing other creatures for support lest the Mystic carrying it die in combat (as it would, being a ½) and then not having anyone else to pick it up. Sword of Fire and Ice, being more expensive to play naturally, relied more heavily on SFM to cheat it into play and equip and then had a less impressive effect than Jitte anyway. Neither card made it worth running Mystics but no other creatures for.

The second major change from New Phyrexia was arguably one of the biggest turning points in recent Legacy history. The hype surrounding Mental Misstep was feverish, hyperbolic and if anything, probably understated. The card changed the way blue decks in Legacy could play, not just because it was the first playable free counterspell since Daze, but because it gave blue decks a 1-for-1 answer to backbreaking turn 1 plays on the draw. Aether Vial and Wild Nacatl, bogeymen of slow U/x control decks, were no longer only answerable by the miserable 1-for-2-off-the-bat trade of Force of Will. This is neither the time nor place, so I won’t go into any further detail, but the point is that Mental Misstep slowed the format down enough so that Jace, The Mind Sculptor became Legacy’s premier blue win condition.

Together, Stoneforge Mystic and Jace, the Mind Sculptor forms the backbone of one of Legacy’s top decks. However, two cards do not make a Legacy deck by themselves. Thankfully, blue just happens to be the best support color in the format (and really, the best primary color too):

4 Force of Will
4 Brainstorm
4 Mental Misstep
2-4 Spell Snare

The standard blue package of counterspells and card filtering, the above 14-16 cards are the basis for disruptive blue decks in Legacy. To quote Luis Scott-Vargas (recognized as one of the best professional Magic players in history):

“All these cards seem like locks in any blue-based deck that has any interest in disrupting the opponent (Merfolk is a whole other subject). All these spells cost 0 or 1 mana, and they all allow you to interact meaningfully with the opposition at any stage in the game. Force and Brainstorm also allow you to filter dead cards very effectively, and it’s no surprise that 90% of my Legacy decklists start with 4 of each.”

These cards are essentially the reason Mystic and Jace are so powerful; when you’ve got the best protection and card selection spells in the format to keep your win conditions safe and ensure you’ve always got gas, it’s difficult to lose. Still, there’s more to a deck than its engine, protection and card selection. Naturally, you’ll need mana to cast all your spells:

3 Island
1 Plains
4 Flooded Strand
4 Mishra's Factory
4 Polluted Delta
4 Tundra
4 Wasteland

The two-color manabase offers U/W Mystic Control several advantages over its competitors, the most important of which is resilience. By limiting itself to just two colors, the deck can afford to play four (!) basic lands to combat opposing Wastelands. As well, since the color requirements are fairly lax (W on turns 2 and 3 and UU on turn 4), the deck can also afford to play two full sets of utility lands, in this case Mishra’s Factory and Wasteland. These utility lands allow the deck to consistently make its land drops each turn and resolve its powerful spells on time, then get aggressive with mana denial and additional equipment carriers/ blockers to protect Jace.

The “industry standard” number of lands for this deck is 24, but professional brewmaster Gerry Thompson has been known to go as low as 22 (link here, may still be Premium) by cutting Wasteland. No matter how many you choose to run, the most important takeaway from this section is that U/W’s primary advantage over other UW(x) Mystic/ Jace decks is its manabase. Adding colors (typically Red or Black) or cutting basics detract from this strength significantly. Before doing either, be sure the cards you add are worth it.

Lastly, the maindeck could never be complete without its utility spells- removal, card draw, additional disruption or equipment, etc:

4 Swords to Plowshares
4 Ancestral Vision/ Standstill
1+ Vendilion Clique
1 Crucible of Worlds
1 Sword of Body & Mind/ other

Even in a post-Mental Misstep world, Swords to Plowshares reigns supreme as the #1 removal spell ever printed. One mana, instant speed, unconditional spot removal with almost no downside isn’t available from any other card or color. Even Path to Exile, a plausible imitator, is an extremely distant second (or third, now that Dismember exists). Since you’re already in white for Stoneforge Mystic, Swords to Plowshares is a natural fit for the deck’s removal slot.

The final slots are given to Ancestral Vision or Standstill (never both, always all one or the other) to provide insurmountable card advantage alongside Mystic and Jace. The correct choice depends entirely on anticipated metagame; Vision is a more powerful option in environments dominated by Aether Vial or slow U/x control decks, while Standstill is stronger in environments dominated by G/x midrange or combo decks. For the moment, Vision is the more commonly occurring card in top 8/ top 16 lists, probably because the prevalence of Jace has forced G/x midrange down and the prevalence of Misstep has forced combo down.

In addition to its known-quantity cards, U/W Mystic Control has a handful of flex slots (2-6, depending on land, Snare and Jace counts). Most players fill these slots with a singleton Crucible of Worlds to threaten Wasteland and Mishra’s Factory recursion, an additional equipment to tutor for with multiple Stoneforge Mystics and some number of Vendilion Cliques for evasive beats and additional disruption. Though they’re technically “flex” slots, the list of cards that actually fit into them is short. Most of the best blue and white spells are already included, so outside of rogue metagame choices or just genuinely suboptimal cards, there isn’t much left.

Sideboard:

Rather than list potential sideboard cards and try to explain their function, I want to take a top-down approach exploring U/W’s weaknesses and what it needs from its sideboard in order to cover them:

U/W Mystic Control typically runs between 10 and 12 counterspells, but only 4 spot removal spells. The exact numbers for this vary since some players run Daze or Path to Exile in the flex slots, but for the most part, the ratio is about 3:1. Jace can pick up some of the slack with his Unsummon ability, but that’s only a temporary solution and not something you ideally want to be doing every turn unless you’ve got a lot of power on the board to end the game quickly. As such, the deck can be soft to creatures. Mystic takes a turn to play and another turn to “untap” (lose summoning sickness) before Batterskull comes online. In that time, most creature-heavy decks will have already established a formidable board presence. Unless you have the exact right combination of counterspells (and even if you do), decks like Zoo, Maverick and Goblins can overwhelm U/W before it has the chance to stabilize.

As well, each of the above decks can deal with a resolved Batterskull (or the Mystic) relatively easily. Half of the Zoo deck is an answer to Mystic or Batterskull, often for cheaper than the cost of either. Maverick’s huge creatures and utility removal can blow right past them, sometimes without even losing cards in the exchange. Goblins is built to overrun blue decks exactly like U/W with swarms of creatures, giant Piledrivers and an insane card advantage engine. I’ll go more in-depth when I do matchup analysis, but for now it’s enough to know that multiple resolved creatures can pose a huge problem. In order to combat this, the deck can board out its slower or CA-negative cards for cheap spot removal, sweepers and additional utility cards. From Owen’s GP list:

1 Pithing Needle (naming Qasali Pridemage vs. Zoo/ Maverick, Aether Vial vs. Goblins)
1 Oblivion Ring
4 Path to Exile
1 Wrath of God

Some of the pros that have played with U/W Mystic Control such as Patrick Chapin mention adding more copies of Wrath of God for its help in the creature matchups. If your metagame has lots of Zoo, Maverick or Goblins, this is good advice to follow.

A second major weakness of the deck is the conditionality of its counterspells. With the exception of Force of Will, all of U/W Mystic Control’s counterspells attack low-end spells costing 1 or 2. The assumption is that anything Misstep or Snare can’t handle, Force of Will, Stoneforge Mystic and Jace, the Mind Sculptor all can. This becomes a problem when an opposing deck can only be interacted with on the stack (rather than the battlefield) and its problem spells all cost more than 2 mana. Neither Mystic nor Jace can affect the stack and Force of Will, while a valuable 4-of, is still a 1-for-2 that every competitive combo deck already has in mind. Decks built around Show & Tell, such as Hive Mind and Sneak Attack, can present a threat that this deck has a very difficult time answering.

Show & Tell decks are among U/W Mystic Control’s worst matchups. Hive Mind is immune to most removal and can Force through its combo with relative ease. Sneak Attack can switch modes by choosing play its enchantment or drop a Progenitus, neither of which U/W has maindeck outs to. It’s not all downside, though; without their namesake cards in play, both decks do stone nothing and have plenty of dead draws. They’re also typically susceptible to aggression backed by minor disruption. Postboard, both matchups get appreciably better (though still poor) because your sideboard brings in a handful of useful cards to replace dead ones. From Owen’s GP list:

3 Meddling Mage
1 Oblivion Ring
1 Vendilion Clique

In a metagame full of decks like this, it’s a good idea to run more copies of disruptive cards like Mage and Clique, or to choose another deck altogether. Fortunately, Hive Mind and Sneak Attack are both relatively underplayed because of how weak they are to Merfolk, which itself is one of U/W’s best matchups.

Overall, the correct sideboard comes down to what your anticipated metagame looks like, the same as any deck. Aside from individual role-players to shore up difficult matchups, there aren’t a ton of cards U/W particularly wants. It does a handful of things very well and some things not so well. The best advice I can give for sideboarding with U/W (or any other deck) is to consider what you want to accomplish and look for cards that help you do it. In order to choose the right quantity, look over your maindeck and count how many cards are bad in a particular matchup. There’s no sense running 7 cards to help you beat something if you later realize you only have 4 cards to side out.

Matchups:

In the interest of remaining intellectually honest, I’m not going to rate matchups on a percentage scale, nor give abstract evaluations of how positive or negative they are (just whether or not they are). The people who write primers are naturally people who play and enjoy the deck in question, so their ideas of how matchups play out can be skewed. Either everything is favorable, or the author overcompensates and nothing is favorable. The fact is, bias exists even if it’s just in explaining card choices. Rather than taking everything here as gospel, test U/W against a gauntlet of the best decks to assess its strengths and weaknesses for yourself.

Merfolk

Merfolk, more than “blue,” is Legacy’s policeman. It does nothing inherently unfair (except cheat on mana with Vial), plays a fast clock and has a monochromatic manabase that makes it the most consistent deck in format. It’s also one of the most heavily played decks, which makes it the first consideration for any deck that wants to succeed in a large field. You may not play against it more than once or twice, but you’re unlikely to play against it less than that. Merfolk is the litmus test for all U/x control and combo decks; it’s not necessarily critical to have a positive Merfolk matchup to win a tournament or even to be a successful archetype, but it does exist, it is widely played and it’s to your benefit to address it.

The most relevant threat Merfolk plays against U/W Mystic Control is Lord of Atlantis and to a lesser extent, Aether Vial (to help resolve Lord of Atlantis). Though its overall synergy and other lords are dangerous, Lord of Atlantis is the only card that makes the combat step non-interactive once you’ve landed your equipments (presumably, your second equipment should be Sword of Body & Mind; the protection here is relevant because Merrow Reejerey can imitate LoA’s effect with it’s tapping). The most important part of playing this matchup, both pre and postboard is to resolve Stoneforge Mystic. You’ve got much greater card selection (they have none) and approximately equal amounts of countermagic. Most competitive Merfolk players have also begun including a full set of 4 Dismember somewhere in their 75.

Whether you win or lose this matchup depends entirely on your ability resolve SFM (into Batterskull), protect them from Dismember and keep Lord of Atlantis off the table. Postboard, you have a lot of help once you double up on Swords effects and add in miser cards like Pithing Needle, Oblivion Ring and Wrath of God. U/W’s strength in this matchup is a particular reason to play this deck over a slower control deck with similar cards, such as UW Landstill or BUG Landstill.

Zoo

Zoo is Legacy’s premier pure aggro deck. In the same manner as Merfolk, Zoo does nothing inherently unfair and plays a (very) fast clock. Most modern Zoo lists are also running a critical mass of 1-drops to overwhelm blue decks’ counterspell suites. It’s a fairly heavily played deck, being the most successful non-blue deck on the SCG Open circuit (Maverick is more successful in Europe). Zoo also has the advantage of being able to cheaply and effectively answer both Stoneforge Mystic and Batterskull with its full burn suite, Path to Exile and maindeck Qasali Pridemage.

Postboard, the matchup could get even worse; Ancient Grudge (sometimes Krosan Grip), additional Pridemages (if they don’t run the full set already) and must-answer bombs like Choke and Elspeth, Knight Errant make Zoo one of U/W’s more difficult matchups. It’s still entirely winnable, since Mental Misstep and Spell Snare are both effective against almost everything they run preboard and you get a ton of help postboard. As with other creature decks, doubling up on Swords and adding in sweepers makes it noticeably easier to stabilize. If the game goes long, you have a much better shot because Zoo will run out of gas faster than U/W and U/W has more ways to refill its hand. A second Batterskull is especially nice in case the first is destroyed.

Maverick

Maverick is one of several G/x (usually G/W) midrange aggro decks that eschews the speed and burn of Zoo for a more stable manabase and bigger creatures. Like U/W, the deck can switch mid game between aggressive and control roles, though where U/W plays a better control deck, Maverick plays a better aggro deck. Against U/W, Maverick is the aggressor, attempting to overwhelm it with early acceleration and fat (for example, t1 Noble Hierarch, t2 Knight of the Reliquary) and follow up with cheap utility creatures like Mother of Runes. Unlike vs. most aggro decks, countermagic is useful against Maverick because stalling into Jace is the best play U/W has in this matchup.

As with other creature-heavy decks, Maverick can be difficult for U/W to beat, although it gets better postboard and is still entirely winnable. You’ll be siding in all of your extra Swords and sweepers and possibly a second Batterskull for when (not if) the first one is destroyed. Hopefully, the frequency with which you side in cards like Path to Exile, Wrath of God, etc. speaks to their strength as sideboard cards. Where other so-called aggro-hosers like Moat, Peacekeeper and Vedalken Shackles would be dead weight against giant Knights and grips full burn, Path, Wrath and their ilk are straightforward and effective.

UW/x, BUG Landstill

Landstill variants share most of their shell with U/W Mystic Control, since they both play similar strategies in similar colors. These decks are all essentially mono blue control splashing other colors for removal. Their particular difference with Mystic Control is the SFM package itself; creatureless Landstill lists fill the extra slots with additional planeswalkers like Elspeth, Knight Errant or Ajani Vengeant and maindeck sweepers like Pernicious Deed or Wrath of God. Though opinions are sure to vary, the Mystic package is an advantage in this matchup because of its reusability. In a matchup that depends so heavily on cards to the exclusion of most everything else, sources of recurring card advantage like Stoneforge Mystic into Batterskull or Sword of (Body & Mind, Feast & Famine, Fire & Ice) are extremely valuable. More than anything, though, planeswalkers and Vendilion Clique dominate this matchup from either side of the table.

Mystic Control has more aggressive early drops than creatureless Landstill variants, which puts in you in the unique position of determining what to fight over. If they allow SFM to resolve, it can threaten a fast clock with equipment. If they counter it, you have a resource advantage when it comes time to fight over Clique and Jace. Their typical methods of recouping lost card advantage (Standstill, Deed, Wrath) range from dead to not good, since after all, these cards are explicitly meant to deal with creature-heavy decks. Rather than drag dead weight in game 1 and side them out for games 2 and 3, you just don’t have them in. It’s worth mentioning that additional copies of Clique and Jace are never dead, even if you already have one on the battlefield. If either remains unanswered, you will probably win. As soon as they are answered, you will want another one immediately. This is true for either side: never, ever let Jace resolve if you can do anything in your power to stop it.

NO RUG

NO RUG has gained in popularity after a string of impressive finishes at GP Providence (3rd) and on the SCG Open Circuit. As a Noble Hierarch deck, NO RUG is susceptible to having its critical 1-mana creature countered or killed before it can accelerate into a Natural Order. Also as a Noble Hierarch deck, it has a tendency to exhaust its hand on early acceleration and then have difficulty recouping lost card advantage. As long as you keep them off Natural Order, this shouldn’t be a problem matchup. Always easier said than done, NO RUG maindecks 3 Vendilion Cliques and runs more free countermagic in Daze, with access to red blasts postboard. NO RUG also accelerates considerably faster than U/W, so racing them to the table with aggressive early drops is a bad idea. Rather, it’s important to stop early Hierarchs from untapping, either through Misstep, Snare on GSZ for X=1, or Swords. Once they’re playing at a reasonable pace, the game should be much easier.

Unfortunately, resolved Natural Order is a legitimate “oops, I win” card on most board states. Preboard games feel about even (you have a game-ending 4-mana sorcery too) and postboard they should get considerably easier. While NO RUG sides in red blasts to fight blue cards, U/W sides out blue cards for white creature removal. Overall, this is a very positive change for you, even if it makes Natural Order more likely to resolve. If the worst happens, you can still race with Batterskull(s) or answer Progenitus with Wrath. Though NO RUG isn’t as creature-heavy as some other decks, many of its spells and lands act like creatures, so additional cheap removal out of the board is still at a premium.

Hive Mind

Hive Mind is as close as it gets to a miserable matchup for U/W, even with a decent amount of help postboard. Permanent removal such as Oblivion Ring, Repeal, Wipe Away and Disenchant all come down too late, as the Hive Mind player never needs to pass priority until the damage is done. Even worse, the deck has functional access to twice the number of Force of Wills on its combo turn because Pact of Negation’s drawback will presumably never trigger. It also has fewer dead draws than most Show & Tell decks, but they do exist. Disrupting their early cantrips with otherwise-dead Missteps and landing early pressure with Stoneforge Mystic is crucial to winning this matchup.

Postboard, Meddling Mage comes down faster than Hive Mind and their only ways to handle it are typically Force of Will and Slaughter Pact. Even off of Show and Tell, assuming the Hive Mind player will drop their deck’s namesake card, Meddling Mage gives you the opportunity to name a Pact before they receive priority. Hopefully, an early Vendilion Clique will provide you with the information you need to guess correctly. Even without it, any guess is better than nothing. Alongside the Mage, Vendilion Clique is your most valuable card in this matchup since it provides information, cycles something important and puts them on a fast clock.

Dredge

Once upon a time, Dredge was an unwinnable game 1 opponent for most decks. In fact, part of its appeal was that it only really needed earn one win per match. Mental Misstep has somewhat changed that dynamic, since countering all of their enablers is now a pretty realistic possibility. Dredge needs to keep or mulligan certain hands based on the presence of specific enablers- mana, discard outlets, dredgers and draw spells and some hands, for example those without a Dredger, are auto-mulligans even if they’re otherwise good. Many cards like Careful Study and Breakthrough have overlapping roles and for the most part, are all easily counterable. Setting Dredge back a couple of turns by countering key spells (conveniently, all 1 drops) can put you very far ahead going into the midgame, where resolving Stoneforge Mystic into Batterskull will end it in short order. However, Dredge is an explosive combo deck that can blow up in your face if it gets the chance, plus many of its cards work just as well from the graveyard as they would in-hand.

For the most part, Dredge’s likelihood to win is heavily dependent on the coinflip of what they actually dredge into and whether or not you have relevant cards. Sometimes, they do nothing while you kill them. Other times, you don’t get the chance to do anything before they kill you. For the GP, Owen ran three Relics to stop graveyard shenanigans, but with the maindeck the way it is, I don’t think they’re necessary. Your countermagic is highly effective at stalling into Stoneforge Mystic and returning Batterskull to your hand will exile any Bridges that manage to hit the yard. Graveyard hate can be very hit-or-miss in an open field and Dredge is not terribly difficult to beat without it. As such, unless you anticipate more abusive graveyard strategies, it’s probably OK to cut Relics for something more widely applicable.

Team America

Team America waxes and wanes depending on what cards are seeing play in other decks. This is because it’s matchups can be very swingy depending on the metagame presence of certain cards, such as Blood Moon and Back to Basics, that can end games on the spot. Among the cards Team America has difficulty beating are Mystic, Jace, Vision and Standstill. Conveniently, these are mainstay 4-ofs in U/W Mystic Control. Predictably, this matchup is one of your better ones. Older versions packing Stifle may prove more difficult (I don’t know this for sure; it’s personal conjecture), but Stifle is poorly positioned in today’s metagame anyway. This matchup typically plays out in the same way; Team America’s hand disruption and U/W’s countermagic trade early until both players’ hands are drained, then Vision, Standstill, Mystic or Jace puts U/W firmly in the driver’s seat until it hits more card advantage spells and the game ends.

Postboard this matchup doesn’t get much worse, as Team America doesn’t play a very convincing BUG Landstill game and all of your best cards are at their actual best. The cards to side in for this matchup might be nothing, maybe extra Crucibles if you’ve got them, or possibly even Path to Exile instead of Sword to Plowshares since they don’t run basics (in which case, Path would just be a slight upgrade).

Rock, Junk & other B/G/x Midrange

Rock, Junk & other B/G/x midrange is not an archetype you will see very often anymore, mostly because it’s a less-powerful cousin to Team America. When Team America is bad, B/G/x midrange decks are really bad. Rather than use this primer as a soapbox for my personal opinions on this deck, I’ll just refer you to the Team America section of this primer. The matchup is similar, except instead of Force of Will, they have Knight of the Reliquary, which means you might want additional spot removal postboard. Either way, it’s another fairly easy matchup. The rise of U/W Mystic Control directly correlated with the waning relative popularity of decks like this and for good reason.

ANT, TES & other Storm Combo

Storm combo is another archetype that has seen better days, though in fairness to them, they used to be amazingly good even when Counterbalance was the most common strategy in the format. Nowadays, skilled storm pilots are rare and their decks are significantly less powerful than they used to be (plus the opposition is more powerful than it used to be). Counterspells and disruptive cards like Meddling Mage and Vendilion Clique are at a premium here, except unlike with Hive Mind combo, all of your counterspells are relevant. It seems fairly straightforward, but save Missteps for Duress/ Thoughtseize/ Chant, Snares for anything they can hit (usually Infernal Tutor/ Burning Wish) and Force of Will for whatever’s left at the end of the spell chain. Batterskull can race Empty the Warrens tokens and the lifegain can make it harder to get a Tendrils kill. Until this archetype gets another boost from new printings (and subsequently, a setback from new bannings), it isn’t necessary to build a sideboard specific to them. Common sense rules apply- side out creature removal and possibly some number of Jaces, side in your anti-combo/ control cards.

Patriot & Esperblade

The final decks I want to touch upon are Patriot and Esperblade. Both of these decks are related to U/W Mystic Control in that they’re all made possible by the power of Stoneforge Mystic into Batterskull and Jace, the Mind Sculptor. Though the matchups are relatively even (you do run almost all of the exact same cards, after all), I believe U/W is at an advantage due to its stronger manabase and the relative lack of importance of splash cards in these matchups. Though they’re not entirely comparable, Standard U/W Caw-Blade created several variant decks, Sparkblade and Darkblade (conveniently, the same splashes for the same reasons as they exist in Legacy).

Both were supposed to dominate the mirror, but time and again U/W proved it was favored. Tectonic Edge (Wasteland), more basics and a better-focused strategy empirically contributed to a positive win percentage for U/W against either splash. Whatever anyone’s justification for either splash to beat the mirror, the fact is that when U/W came up against either, it won more often than not. Much like Standard, though, these matchups are skill-intensive because of the high level of interaction. Minor advantages aside, the better player will usually win. These play out much like vs. Landstill variants, except closer to a true mirror. The best you can do is side in your anti-control cards and play well.

These builds in general seem heavily geared towards fighting against combo and other blue decks. It looks like your best bet is going to be something like Zoo, Goblins, or Maverick, which can outclass or overrun their threats.

Some of these manabases seem somewhat optimistic. I'm not sure why Team America isn't doing better here. If you're going to play Merfolk in a Blade Control heavy meta you should think about Stifle main.

These decks are light on sweepers and answers to resolved permanents generally. For some reason a control deck that is very light on creature count has decided its backup win condition is going to be an incredibly fragile flyer. I would think one would want that in the board for combo if anything, but I've never understood the fascination with that card exactly.

Most lists are also only running one Batterskull and so incredibly vulnerable to Pridemage or Vindicate, the latter of which will also hit their other bomby threat, Jace.
