Alteration

Kicker {b}{b}{b/r}
Mutate target creature an opponent controls
under another creature they control. The
creature on top becomes a 2/1 black and red
skeleton with "This creature cannot block."
If this card was kicked than also reveal cards from
the top of your library until you reveal a
creature. Mutate that creature either on top or
below another creature you control, then shuffle
your library.
