Aging Untouchable

When this creature enters, each opponent sacrifices a creature with the greatest power among creatures they control. You gain life equal to the greatest power among creatures sacrificed this way. Madness—{2}{B}, Pay 8 life. (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.) Gift your madness to our Lord. Bless our brethren with grapes. Take care that they fully ripen.{/fontsize-29}
