Gargoyle of Subterfuge

Flying
Whenever Gargoyle of Subterfuge deals combat
damage to a player, that player reveals their hand.
You may choose a non-land card from it. If you
do, that player discards that card.
City Devourer - At the beginning of your upkeep,
you may exile a land card from a graveyard. If
you do, put a +1/+1 counter on Gargoyle of Subterfuge.
