The Madcap Jester Foil

Legendary Creature — Clown Wizard

Whenever The Madcap Jester attacks, each opponent exiles the top card of their library. Whenever a spell or ability you control causes one or more cards to be exiled from an opponent's library, you may play those cards until the end of your next turn. Mana of any type can be spent to cast spells this way.

He who bears the cap laughs last.
