Jeskai Infiltrator | Creature | Human Monk | Jeskai Infiltrator can't be blocked as long as you control no other creatures.
When Jeskai Infiltrator deals combat damage to a player, exile it and the top card 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.) | Cynthia Sheppard
Marang River Prowler | Creature | Human Rogue | Marang River Prowler can't block and can't be blocked.
You may cast Marang River Prowler from your graveyard as long as you control a black or green permanent. | Yefim Kligerman
Shu Yun, the Silent Tempest | Legendary Creature | Human Monk | Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
