Eli's Polymorph

Exile target nonland permanent. That permanent's controller creates a 0/4 blue wall creature token.

Splice onto instant or sorcery {p/u}{p/u}{p/u}{p/u} (As you
cast an instant or sorcery spell, you may reveal this card from your hand and pay its splice cost. If you
do, add this card’s effects to that spell.)

"Murgur Murgurgle!" — Eli, Arch-Comedian Wizard
