Sinister, Man of the Pocket

Sneak 2 (Whenever this creature enters the battlefield or deals combat damage to a player or planeswalker, you may hide 2 cards from your
hand under the table or another place. You may sneak these cards onto the battlefield without paying their mana costs, but if an opponent sees
you play a card this way, exile it.)
