Cryomancer Quinn

You may sacrifice target creature and artifact,
and if you do for the rest of the game it has
"All creatures and artifacts being cast from the
hand gain 'After it was cast from the hand, but
before it resolves, exile this card. At the beginning
of your next upkeep you may cast it from exile
without paying its mana cost.'"
From humble beginnings to everyone's pet....
Ill show them! - Quinn Galleybeard
