I played a few Legacy tournament matches as well as quite a few in-real-life practice games yesterday with the following list:
20 lands (9 fetch, 4 sea, 2 bayou, 1 trop, 4 waste)
4 delver
4 DRS
4 goyf
1 tombstalker
1 liliana otv
4 FoW
4 daze
4 bstorm
4 ponder
4
FATAL PUSH
3 abrupt decay
3 hymn to tourach
SB:
3 spell pierce (should have 1 of them be a Flusterstorm and/or Invasive Surgery)
2 u. jitte (could consider cutting 1 for something else, e.g. Jace TMS)
2 s. extraction (could be split with a G. Cage -- BR Reanimator is on the rise)
2 tsieze (could be something else if combo isn't as prevalent)
2 pithing needle (should be a 1/1 split with Null Rod)
1 s. library
1 darkblast
1 dread of night (simply because there's a lot of D&T in my meta -- could be something else)
1 Leovold, spymaster of trest
The sideboard felt a little lacking at times and was thrown together without a ton of consideration, but I can definitely say that using
Umezawa's Jitte as a form of board control actually worked
*extremely* well in comparison to alternatives such as Toxic Deluge or Golgari Charm. In certain metagames you might want some number of those *in addition* to a Jitte or two, but I was amazed by just how much landing even only one swing with the equipment controlled the board.
I liked bringing in Leovold in against all sorts of decks, though he does feel a bit 'win more' -- he's great at helping to hammer in that final nail when you're a little bit ahead, but he doesn't seem to do a whole lot of work if you're behind. Hence, I'm not quite as blown away by him in this deck as some people seem to be and am unsure if he really warrants main-deck inclusion. I think he makes a lot of sense in the main of a midrange build that's running more creatures, but in a Delver shell he seems like more of a sideboard card.
The maindeck is basically just the classic Signorini tapout-style, except with making a few minor cuts to make room for 4 copies of
Fatal Push. I can say
confidently that this addition has made the deck significantly stronger against ALL forms of aggressive decks in a major way. Having a turn 1 answer to things like Deathrite Shaman or Mother of Runes is just SO important, and furthermore it helps free up your copies of Abrupt Decay to use against various non-creature problems.
The classic list was already favored against other forms of Delver, but now I think it's HEAVILY skewed in Team America's favor -- like 70-30. Consider the following advantages in a Delver mirror:
-running 20 lands instead of 18, less likely to lose to Stifle/Waste, more easily able to avoid getting Dazed/Pierced at inopportune moments
-you have 5 large Bolt-proof creatures, 1 of which happens to block Delvers quite nicely and generally can outsize other Goyfs
-against RUG, you have DRS and Liliana which can go over Mongoose
-7 removal spells to pick off basically any threat -- and the 2-mana removal can't be countered
-resolving a Hymn is backbreaking for a deck that can't recoup card advantage
Basically, my assumptions about how FPush would change the dynamics of this deck were correct: the addition of 1-mana removal has increased the power of this deck in a MAJOR and tangible way. Making room to incorporate the full playset just makes the deck so much more solid against creature-reliant decks, and yet TA is still able to maintain it's amazing flexibility and power against basically every deck archetype, and arguably the best form of the Delver archetype. To give a specific example, an advantage it has over Grixis is a more stable manabase and access to Abrupt Decay -- making it so you don't just lose to something like a resolved Counterbalance or Chalice of the Void. Lightning Bolt definitely has it's advantages, but not dying to 4+ toughness creatures has its perks too.
Some areas to explore:
1. Would an 18-19 land, lower-to-the-ground BUG Delver list work well, or does the lack of Lightning Bolt still matter
2. What would an ideal list incorporating Dark Confidant look like?
3. Is a straight UB (no tertiary color except perhaps as a minor splash) Delver list feasible now? Being able to run basic lands seems good.
