Swamp= Illness in the Ranks. (B-> Tokens get a -1/-1 counter on them.). The idea is simple. Make a bunch of tokens that are all 1/1's, let them die with the illness, the lattice makes them artifacts, and the disciple kills the opponent. Never have to attack to win. And with flicker, it's a fast win condition.
To abuse a card in this set, though, go with Assemble the Legion and let it go off a turn at a time.
