I actually have no opinion of this, never played with or against it. Probably never will!
I mean, it's a 5/5 for 4 and has some flavor text. 2.5/0.0/1.5

I can tell you that turn four this, turn five Call of the Full Moon won me a few games. The ability could just as well be flavor text in Limited, but it's a solid beater that demands a fast answer.
