The main downside to Island is that it allows opposing Cold-Eyed Selkies to attack. This is best handled by Swords to Plowshares.

I realize you're being facetious, but the strange thing is that in Vintage, the choice of playing basic lands, and how many, actually is a thing. There is another thread going on discussing whether a Grafdigger's Cage that just affected LANDS would be a good thing to print, and it poses the same question; how limited are Vintage decks by the mana base they have to run? At the moment, Wasteland punishes you for running four or five color decks full of Duals and Cities, so people tend to rely more on 2 or 3 color decks with a very occasional 4th splash. Every mana base seems to be based on fetches, a few duals and utility lands, and basics. Stfile isn't played widely enough to be much of a threat to these kind of manabases. Would a truly effective fetch hoser force people into 1 and 2 color decks? Would this be healthy for the format?
Anyway, back to M13. Yes, Tormod's Crypt is probably gonna see play, but thats a degenerate answer. So is Island. And Duress. Im going with Tarland, Sky Summoner of the new cards spoiled thus far. Yes. he's vulnerable to removal, but he probably does win the game pretty handily if you get to untap with him even once or twice. I can imagine him as a singleton in a Drain Tendrils type list, OR in a Landstill build.
