One of the traps of creating cards is to put too much text on it, to make it stand out, or have it create 5 different cards or some ridiculous jack-of-all trades bs.  As for your card, it's a bit contradictory to what it's meant to do. If you are being rushed down, you don't want to take extra damage. If you don't face an aggressive opponent, then it's a 4 mana 7/7 I guess. Not bad, but not impactful enough for wild.
