Phyrexian Abomination

({p/b} can be paid with either {b} or 2 life.)
Trample, haste
When Phyrexian Abomination enters the battlefield, if you paid 6 life as part of its casting cost, each opponent loses 6 life. If you paid {b}{b}{b} as part of its casting cost, each opponent sacrifices three permanents.
Everyone runs and everyone dies.
