Other nontoken zombies you control enter the battlefield with an additional X +1/+1 counters,
where X is the number of creature cards in your graveyard.
{2}{u}{u}{b}{b}{r}{r}{g}{g}{t}: Remove each +1/+1
counter from each zombie creature you control.
Each opponent loses X life, where X is the
number of +1/+1 counters removed this way.
