No, SwordDanc does nothing on metals. It's basically a critical attack, or nothing. (EDIT: And, there are basically no skills that can crit, *except* for EvilSlash.)
EDIT 2: On the plus side, MetalKings are vulnerable to turn-loss abilities, so the other 3 members can all focus on keeping the MetalKing from running. Bark/BoxerDanc/SpiderWeb, specifically.
You can also use Time Sand to reset a battle if the target flees, but other enemies remain.
