I'm still waiting for someone to bring up the invisible archer paladin as a strategy (after the invisible paladin and the archer paladin).
Oh wait. Imagine a group of doppleganger archer paladins. They all polymorph into the same person, delay their actions to move and attack at the same time: the target can't recognize who shot him since they all look alike. Add in a warlock multiclass for eyebite so that the one who really shot him is additionally invisible.
Another one: the paladin multiclasses in wizard. He gets the mirror image power. Would attacking his image count as attacking the paladin?
Bah. I still prefer my first idea. The paladin teleports behind a wall next to the target or under the floor under the target, still adjacent to it, after his attack. Simpler.
Players who want to play the paladin class like this need to multiclass as lawyers
