Pardon if I sound a bit derogatory, but aren't you just listing it's strengths here?
Don't worry, I'm just criticizing a bit. No harm meant, no offense taken.

Anyway, yes, but its weaknesses are summarized by this fact: you need to have a creature out for a whole turn before playing it. That's what it is, really, since lobo effect is possibly a PLUS (as it is more versatile and you're going to use it to increase attack power anyway), and summoning sickness means you have to wait a turn rather than wasting it sooner.
