Changeling

Whenever this card is tapped, create a 1/1
blue Illusion creature token with changeling.

{1}{t}: Exile the top 3 cards of your library. If
any of the exiled cards are creatures, you may
choose to cast one of the exiled creature spells
without paying its mana cost. If you do,
it becomes an illusion horror in addition
to its other types.
