Dizang the Untouched

Enlightened (Whenever you cast a noncreature spell,
this creature gets +1/+1 until end of turn.)
When Dizang the Untouched deals combat
damage, you may cast a sorcery spell from your
hand with mana value less than or equal to that
damage without paying its mana cost.
{2}{u}: Return Dizang to your hand.
