Locked cards lose their card effects until they're unlocked. I don't think there's a way to word that properly? And anyway, getting the opponent's ability sounds cool, but it is very hard to adapt any styles into LJ's plays. Sometimes the skills you copied wouldn't even help anything.

And the ability you said is OP by the way. It is extremely under-costed.
