{t}: Add {b}{b}.
{t}, Pay {b}{b}: Tap target creature. Put two +1/+1 counters on it until end of turn. If that creature loses life and survives this turn, remove all +1/+1 counters from it at the end of the turn instead of letting it die. If the targeted creature was controlled by you and it survives, add {b} at the beginning of your next main phase.
