@ Eric: Theme is "Cards that allow a monster to attack twice during the same Battle Phase"?
Anyways. I can think only of one thing:
Ahem...
Good for those things that don't have an effect, like the Gem-Knight Pearl on the card picture.
The problem is, IIRC, there are only 2 Xyz monsters in OCG/TCG that doesn't have an use for their materials. And then again, Blade Armor Ninja can perform the exact same thing.
I don't really see an use for this card, other than the cool factor of making a stand pose, yelling manly, stopping time and throwing a swarm of punches to your opponent, letting them know how futile are their efforts.
Traditional: 0/10 Do we have Xyz monsters desirable for Traditional, other than maybe Roach?
Advanced: 4/10 Not useless, but eh. If you really want to double attack, go with Blade Armor Ninja.
Art: 10/10 ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA!!!
