Kuman, Renegade Prismancer

Whenever a legendary creature enters the battlefield under your control, you may have it
enter with a -1/-1 counter and a prism counter.
Creatures with prism counters on them don't
have the same name as any other card for any purposes.
"I found myself that day. As a matter of fact, I found
a lot of my selves."
