Joker, Phantom Leader

Hold up! — Whenever an attacking Rogue you control deals lethal combat damage to a creature, you may prevent that damage. If you do, choose one — • Lend me your power. — Gain control of that creature until the end of your next turn. It becomes a Rogue in addition to its other types until the end of your next turn. • Show me the money.. — Create a number of Treasure tokens equal to that creature’s power. • I want an item. — That creature’s controller reveals cards from the top of their library until they reveal a nonland permanent with mana value less than or equal to that creature’s power. You may cast that card without paying its mana cost. Then they shuffle their library.{/fontsize-36}
