Gyarados, Depth's Might

Flying, trample
Whenever Gyarados deals combat damage to an opponent, return up to that many creatures
and/or planeswalkers from that player's field to
their hand. Then, you may put that many
+1/+1 counters on Gyarados if it defeated a
creature or planeswalker this turn.
- Gyarados costs {u}{u}{u}{u}{u}{r}{r}{r}{r}{r} if it is
in your starting deck.
