Mystical Illusionist

Wizard offering (You may cast this card any time
you could cast an instant by sacrificing a Wizard permanent. If you do, the total cost to cast this card is reduced by the sacrificed permanent's mana cost.)
When Mystical Illusionist enters the battlefield,
if its offering cost was paid, counter target spell. Otherwise, create a 2/2 blue and red Drake
Illusion creature token with flying.
