How do you plan on powering up the four energies again before it gets knocked out a second time? Also, just about any attack from an opponent would reduce the amount of times you can use the attack from three to two.
That being said, it is a basic so Fighting Fury Belt would give an extra 40 HP.
I don't really think this would be good in a competitive deck, but could see success as a fun deck at league.
Not sure if you play expanded at all, but Protection Cube from Flashfire eliminates the self damage from attacks.
