I really like his ability to gain armor! At 5 stacks, he takes virtually no damage. He can negate many BB3 moves and even get a punish afterwards! Now, instead of trying to sacrifice my weakest character to a BB3, I just have him tank it! Even better, the taunt moves that give armor are actually useful now. I think he's worth investing into! I don't know how he compares stat-wise to natural gold units. I hope he is still good end-game.
