Assuming that nobody else can pay for the costs (I have all the diffrent pact spells from the various colors.)

I was opening up my m10 box, and thumbing through my newly aquired cards when I found hive mind. I'd seen it before at a limited prerelease, and was about to throw it into my jank rare pile when i realized how great of a multiplayer card it could be. Later that day, I was at the card store playing with someone, and saw them play summoner's pact. (u know, the one that makes you pay mana at the start of the next turn's upkeep or you lose.) Then I remembered hive mind from earlier. Hehe. I then through together some of the pact cards i have and mana ramp, and now i have a cool new deck. All I do is ramp and tutor to find the hivemind/ pact cards. Then after playing hivemind, I play 2 of my pact cards (usually of different colors). Everyone copies the spells. Everyone loses the game at the start of there upkeep, and by the time it gets to me, everyone has lost the game, thus making me the surviving player.
