Sorcery, 2W (3) Remove target creature with the greatest power from the game. (If two or more creatures are tied for greatest power, target any one of them.)1 "Let all witness the fate of those who defy me." -Crovax

It can only target a creature with the greatest power. This means you pick such a creature on announcement, and if that creature is not still the one with greatest power on resolution, then this spell is countered since its target is illegal. [Nemesis FAQ 2000/02/07]
If the creature with the greatest power (or all the creatures if there are more than one) are untargetable, you can't cast this spell. [DeLaney 2000/02/21]
