So, I did terribly in any event. For one, I feel the deck needs Snapcaster mage--decks these days are too good at not dying to die to our shit. I could have won many, many more games had I had snapcasters in the deck (which I fortunately traded for +3 Snapcaster's and +1 Volcanic Island at that very tournament, I'll be posting what my new decklist is going to be afterwards).
I'll briefly describe the games since most of them were somewhat linear in nature..
Match 1: UWR(?) Patriot control thing..
This was probably UW tempo, he dropped Volcanics, but in both games I never saw a red card..I can only imagine VI's were in play for some reason, so I'm fairly certain it was some Patriot variant.
Jitte hit the table, I got wrecked, I boarded for Jitte, it got countered, Jitte wrecked me. Fetched mostly basics, PoP never hit for more than 2.
Match 2: UWG(?) Bant control thing..
Again, green there, never saw green cards, after the games he let me know that it's for the 2x Sylvan Library's he ran..
Jitte hit the table, I got wrecked, I boarded for Jitte, I killed Jitte early, Jace + Elspeth beat me while he fetched basics / spell snared what worthless PoP's I could cast.
Match 3: Deadguy Ale
I really should have won this, game 1 I just didn't make it there before (Guess what!) Jitte hit the board and wrecked me. Game 2, I keep a one-land hand with a brainstorm, otherwise solid, land is a basic island, bad call. Brainstorm, nothing. Somehow I go through 26 cards before finding...another basic island. This was the only game in the entire tournament where 18 lands hurt me, they were all clumped up (after stack shuffling) on the bottom of my library. I took him to 2 life with 2 delver's before he stabilized, got a jitte(!!) and killed me. I was kind of disappointed and frustrated at this point that 5 games in a row jitte just absolutely dominated my shit and wasn't thinking terribly clearly. A mulligan to six and I would have won the series, I'm rather confidant of it--we played like 3 or 4 more games because the guy was very nice and I won most of them.
Match 4: Super jank mono red burn
I won, he cheated a lot (frequently wouldn't take damage from being hit, was adding buffs to Kiln Fiend off of creatures, didn't tap to play things) but I didn't really care because it was like a 100 card super casual burn deck. He asked if it would be cool if we played 3 games no matter what, because we're here to play magic, and I'm like yeah whatever, so I win 2-0, we play again, I keep some dumb hand because I don't really care, he wins and reports the score as 2-1--he was a really nice guy, this kinda bothered me though. Overall, I didn't really care because I was clearly not in top8 and I don't really give a shit, but in retrospect if he wants to play in more tournaments I probably should have called him out (in a nice way obvi) on everything..
Match 5: GW Maverick
Narrowly lost game 1, game 2 I got blown out. Game one he had 4 non basics in play, I PoP > Fireblast > Lightning bolt for 15, he's at 14, he STP's his own thrun and lives, stabilizes, beats me to death with an arbor carrying a sword. Game two he plays around PoP (at one point even just burning his own lands with wasteland) and I lose..
It's true, Snapcaster Mage is a card for decks that want to see the mid to late game, but more importantly, it's a card that operates in the mid to late game very well. Just because this deck can win fast on a goldfish, doesn't mean it'll ever happen. In every game I played, my creatures were removed, my PoP's were countered, people hardcore played around PoP with surprising numbers of basics (UWR had 4 islands and 2 plains out at one point).
Mana was never really an issue except for that one flukey game, I frequently had 2-3 mana in hand each game, but not a single game went quickly. People run counters, lots of them, oddly enough I was never hit with a force once--just spell snares and pierces and dazes. Getting my VI wasted was literally never relevant, it happened a lot but it didn't really impact the game. The only remotely fast game was against Maverick and it was because he didn't play around PoP and it blew him up hard, and then he lived, I didn't top deck a bolt and lost.
Here's the new list I'll be running:
//Creatures:
4x Goblin Guide
4x Delver of Secrets
3x Grim Lavamancer
3x Snapcaster Mage
//Spells:
4x Lightning Bolt
4x Rift Bolt
4x Daze
4x Brainstorm
3x Price of Progress
3x Ponder
3x Lava Spike
3x Spell Pierce
//Lands:
2x Volcanic Island
2x Mountain
2x Island
4x Arid Mesa
4x Scalding Tarn
4x Misty Rainforest
//Sideboard:
3x Submerge
2x Fireblast
1x Price of Progress
3x Tormod's Crypt
3x Smash to Smithereens
3x Pyroblast
I've been to about three tournaments now, none of them particularly large--between 30-40 people--and I've only ever seen 0 people playing combo so, mindbreak traps are out. Eventually, Submerge will be some more useful artifact hate. I really hate Jitte. I might even just board some Jitte's...to kill Jitte's.
