Gimball's Showdown

As long as you control Gimball's Showdown, Clown creatures you control get +3/+3 and have Juggle (Whenever this creature enters the graveyard from anywhere, that creatures' controller may draw or discard a card.)
{2}{t}: Target Clown has haste until end of turn.
Gimball was one move away from victory. "What has two thumbs and declares checkmate?" he asked.
