Toon World

Hyrulean Knights are also toons & all toons have {p/g} Regenerate & Skulk. If a Non-toon creature would die, you may sacrifice Toon World to Regenerate it, except it's also a
toon with {g/u}{r/g} Regenerate & Skulk.
Oh dear I'm afraid you're about to enter a world
of pain. A world of chaos! A world of absolute mayhem! That's right; a world of TOONS!
