Joker, Phantom Thief

At the beginning of combat on your turn, choose
a keyword from among the following that Joker
doesn't already have: flying, first strike,
deathtouch, hexproof, lifelink, menace, reach,
haste, trample, and vigilance. Joker gains that
keyword until he leaves the battlefield.
Whenever Joker deals combat damage to a player, create a Treasure token for each unique keyword
Joker has, then choose one: put a +1/+1 counter
on Joker; or draw a card.
