Newborn Chimera

Hatch 1 — {r/g} (If you cast this spell for {r/g}, put it
under target non-human creature you control with
a hatch counter on it. The creature on top gains all
of this creature's abilities. At the beginning of each
upkeep, remove a hatch counter. When the last is
removed, exile this creature, then return it to the
battlefield under its owner's control. It has haste.)
