Kami of the Forgotten

Flying
Whenever Kami of the Forgotten deals
combat damage to a player, put a +1/+1
counter on it. Then, if Kami of the
Forgotten has three or more +1/+1 counters
from it, that player reveals their hand. You
choose a nonland card from it. That player
discards that card. Otherwise, that player
discards a card.
