Darth Nihilus must attack each of your turns. If he doesn’t or is unable to, pay 2 life or sacrifice a creature at the end step.

4{b}, tap: destroy target creature. It can’t be regenerated.

If a creature is sent to the graveyard due to Darth Nihilus’s card effect, gain X life, where X is that creature’s toughness.
