Zamasu, Distorted Justice

Flying, first strike, lifelink

At the beginning of your end step, if you
both own and control Zamasu, Distorted Justice and
a creature named Goku Black, Herald Of Ruin, exile them, then meld them into Fusion Zamasu, Divine Radience.

"I've taken godhood to a new level. Divinity made perfect. With a body that befits a Kai, One that is invincible."
