Dorcas and Rex have 7000 defense. That usually requires a link attack to kill. And since Duel Law drains your opponents gauge if they want to do that, it's fairly effective.

Yeah, I recommend 7-8 weapons. And Battle Aura Circle is there to stop attacks when your center gets blown up. Having a monster in the center usually doesn't weaken it.
