So have you guys seen Adam Prosak's "Oops - All Spells" Legacy list featuring some innocent looking cards from Gatecrash? (I prefer "Look Ma - No Lands!") He's claiming turn one wins at a rate far surpassing that of Goblin Charbelcher decks.

You can goldfish it here; it seems remarkably consistent, and perfect if the meta is still full of decks without Force of Will.

TLDR: use the Belcher plan of free mana (Spirit Guides, Chrome Mox, Lotus Petal, etc) and rituals (Dark Ritual, Cabal Ritual, Grim Monolith) to cast one of the black creatures that "grinds" a player (Balustrade Spy, Undercity Informer). Except - wait for it - you have no lands.
So you flip your library into your graveyard, putting 3 Narcomoeba into play, then flashback Dread Return on an Angel of Glory's Rise, putting Laboratory Maniac and Azami into play, then draw a card and win the game. If any of the combo pieces are in your hand, you can always Cabal Therapy yourself to get them into your yard...
