There are lot of formes that TCG-wise might be associated with Kalos (like Zygarde or certain Mega Evolutions) but which in fact are unobtainable in X&Y, which is why I asked - hyperbolically - if all formes from Kalos Pokédex Pokémon that came out in games after X&Y would be admitted.
I think...
@Jabberwock I guess non-Kalosian formes like Zygarde Perfect and Mega Audino are legal for this month's CaC, would this go as far as Pikachu Gmax and such?
I'm dropping too, sorry! I couldn't find any interesting ideas until yesterday, but now I'd need at least one more day to work on it ? maybe I'll be able to use it on a future CaC. Can't wait to see the results, I've seen a lot of great entries!
