Goretooth the Awakened

Trample
When Goretooth the Awakened is turned face
up, it fights target creature opponent controls. If Goretooth the Awakened survives, regenerate it
and it fights another target creature. Repeat this process up to three times.
Morph {5}{g}{g} (You may cast this card face down
as a 2/2 creature for {3}. Turn it face up any time for
its morph cost.)
