Eli'Jah, Circus Conductor

{2}{r}{b}: Target Non-Commander creature loses
all abilities and becomes a 2/2 Clown.
Clown With Taste - At the beginning of your end
step, for every opponent who controls a clown,
you may exile the top card of that player's
library. You may cast that card until the end of
your next turn, and spend mana as if it were
mana of any color to do so.
