Hello, I'd like to know if it's possible to use naval (or anything that requires performing like Takasho, Spinning Heel Kick or Iron Will) with cards designed for Ivory arc - ones especially from GoC. All of those cards targets "your target personality" not "your performing personality". If the answer is that you can't (which I suppose will), would there be any errata/clarification to allow those cards to better fit current environment?
Naval Invasion: Reaction: After engaging, once per battle, if you are the Attacker and your current army has more Naval cards than the side oppos¬ing it, choose your performing Naval Personality: You have the first opportunity to take a Battle action, which he must perform."
Takasho: Battle: If any enemy units are at the current battlefield: Move Takasho there. You may take an additional Battle action which Takasho must perform.
Friends in the Jungle: Battle, 1: Give your target Nonhuman Personality +2F/+2C.
Iaijutsu Dojo: Iaijutsu Battle: Your target unbowed Personality challenges a target enemy Personality. Dishonor and bow the duel's loser.

It is not, unless the card otherwise fits the rules for Performing (an action on an Item or Spell with the new templating will still be performed). I think it's safe to assume that design has a plan to make these work with Naval in Ivory, but for Emperor Edition, nothing has been announced that would allow them to be used.
