All Might vs. Ryuk

Choose a legendary creature you control and a
legendary creature you don't control. Those
creatures fight each other. If one of those
creatures dies this turn, exile it instead. If neither
of those creatures die this turn, destroy all other
creatures at the beginning of the next end step.
Ryuk: What?... That's not me!
Light: The resemblance is striking.
Ryuk: No way.... and stop laughing!
Light: Finally, I'm not the punchline!
