This seems ridiculously powerful. Getting 16 power with haste on turn four seems to be completely broken. Maybe restrict the activation to once per turn?

Or, you know, an extra activated ability of would keep this saner. Would still be spectacular. Personally, I'd probably err toward , but I'm guessing the card needs to be tested to get a full understanding of what feels right.

Of note: This card makes a pretty solid defensive card, too. It's also one of those rattlesnake cards that you never need to activate the ability to seize control of a group game, since no one will attack into that. Maybe those elementals should say "This creature can't block."

Really? My instinct is "I can attack you, lose a few creatures; and you're crippled forever? CHARGE!"

Nerfed even more, still probably a great finisher for a red aggro deck.
