the cost of 3 makes it weaker, cause in decks, based on spirits (or rainbows with quantum towers or only a few burnings), its all about speed, the "real" difference is the +1 defense, rest is pretty the same (cause same attack at the same time).
if cost stays the same (maybe with stats 1/2 or 1/3), it would be far more usefull. (or as it is with +1 defense to survive an owls eye hit, a fire storm, etc)
