Toon World

Toon creatures you control have hexproof and protection from non-Toon creatures.
{u}{u}{b}{b}, {t}: Gain control of target non-Toon
creature. It becomes a Toon in addition to its
other types. Activate only as a sorcery and only
once each turn.
Whenever Toon World leaves the battlefield, sacrifice all Toon creatures you control.
