Manabase:

4x Prairie Stream (Who can afford Tundras?)

4x Sunken Hollow (Who can afford Underground Seas?)

4x Polluted Delta (Fetch the perfect manabase)

4x Flooded Strand (Fetch the perfect manabase 2.0)

1x Island (I worry about Wasteland)

1x Plains (I worry about Blood Moon)

1x Swamp (Just in case)

Beats:

4x Jace, Vryn's Prodigy (He's a staple! I also spent $280 on the playset and I don't want to see that money go to waste. He's also better than Snapcaster because he can be reused, and if he's more expensive than Mind Sculptor he must be better, right?)

4x Thing in the Ice (I can't afford Goyfs)

4x Dragonlord Ojutai (To trigger Silumgar's Scorn)

Interaction:

4x Path to Exile - FNM Promo (I could use Swords to Plowshares but gaining my opponents life goes against my strategy of beating to 0. And no one except for me plays basic lands in Legacy)

4x Silumgar's Scorn (I couldn't find Counterspells at my LGS)

4x Thoughtseize (Thank god I had these left over from THS. I heard combo is everywhere so I)

1x Misdirection (It's almost as good as FoW, which I can't afford. Good thing I opened this in Conspiracy draft)

4x Stifle (It's too good for Modern apparently so that means it's good in Legacy, right?)

Gas:

4x Brainstorm (The most skill testing card, instant 4 of and if we play Legacy we play blue, right?)

4x Ponder (Brainstorm 2.0)
