[@sMoKe] I think it would significantly injure said pokemon, but Id prefer to avoid them dying so soon. I'd say it'd hold the same 'laws of physics' as everything else. Maybe a few broken bones.. say if a pokemon were to use razor leaf or [i]cut[/i] on another pokemon, if the bleeding didn't get taken care of, they'd bleed out. So, feint, and if not taken care of soon, death.
