Infinity Big Bang Storm

As an additional cost to cast this spell, sacrifice
two nonland permanents. Infinity Big Bang
Storm deals X damage to each creature target
player controls, where X is the combined mana
value of the sacrificed permanents. Remove all counters from each creature that player controls
that are not destroyed this way.
Burn in the everlasting hellfire of creation! Be utterly annihilated, down to the very last scrap of DNA!
