Yuta, the Cursed Child

Whenever Yuta enters, search your graveyard, hand, and library for a card named Mimic Vat, put it onto the battlefield, then shuffle.

Tokens created with Mimic Vats are instead Legendary creatures named Rika Queen of Curses with Devoid, Trample, and Vigilance and have base power and toughness 7/7 in addition to their other types and abilities.
