Yah a good board wipe is necessary in any multiplayer deck. Evacuation, Pyroclasms, Mutilate, Wrath of God, yah you gotta have something to deal with a heavy board. Some players hate when you do crap like that but hey to win multiplayer you gotta be able to clear out the board occasionally ;D
Multiplayer really lets you play big fun spells, that hasta be my fave part about it *Timmy moment.* Oh btw Proxyt, I'm Aaronock, when we partied I played my bf's HP who is Kittypuff xD
