I know, I know.  Done to death and cheap as hell.  Surprisingly, it's actually a pretty strong deck and kinda fun to play.  Infect threats are almost psychological, because opponents don't inherently understand how to deal with them.  Facing down an Infect-powered attack is confusing because blocking so rarely seems advantageous, yet is absolutely crucial as the distance from 0 poison counters to 10 is very, very short.

If you can stick an early threat and sneak in a few buffs, then you can win the game very early.  Turn 3 maybe?  If not, the deck has the tech to extend into the midgame, although it could stand for some acceleration to be added so that quick wins are more consistent.

Extremely important note: Melira, Sylvok Outcast and Sword of Feast and Famine WRECK this deck.
