Jintoro, Kojo Jonin

Jintoro, Kojo Jonin can't be blocked as long as you control no other creatures.
When Jintoro, Kojo Jonin deals combat damage to a player, exile it and the top three cards of your library in a face-down pile, shuffle that pile, then manifest those cards. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it’s a creature card.)
