Korvold, Callous Tyrant

Flying, trample, haste
If a permanent being sacrificed would trigger an ability, that ability triggers an additional time.
At the beginning of your end step, put X +1/+1 counters on Korvold and draw X cards where X
is the number of permanents that have left the battlefield this turn.
If you haven't an offering when you arrive, don't
arrive alone.
