Comm error when battling friend with shiny hoopa (unbound)

[Neocentennial]

Hey everyone I am stuck in an odd situation and each time I try to battle my friend wirelessly with my shiny hoopa the comm error screen pops up while we are choosing are pokemon. From what I can tell it seems pretty legit to me but I may be overlooking something. I have tried multiple times with many multiple combinations of memories and still I cant get it to work. Anyone have a ekx file that does work? Thanks in advance also here is an example of a hoopa I have attempted to use but like I said I tried several different variants;

Moveset:

Psyshock

Shadowball

Hyperspace hole

HP Fighting.

Met route 2 OR cherish ball

modest

level met 100

memories : Hoopa met Bicentennial at... a riverside road. Bicentennial threw a Poké Ball at it, and they started to travel together. The Pokémon remembers that it got nervous.

Hoopa became Bicentennial’s friend when it arrived via Link Trade at... somewhere. The Pokémon remembers that it had fun.

Thanks in advance as I am off to bed and any help will be extremely appreciated !

Hoopa isn't obtainable yet.

well yeah but how are people using it in friend battles on youtube? Maybe its local only? also im slightly referencing this post, http://www.reddit.com/r/PokemonPlaza/comments/2mmuq5/info_hoopa_now_tradeable/ so maybe I can not use it because it is shiny?

Hoopa was tradeable for only a day or two before it was patched.

It can't be used in online battles at all. Local battles, sure.
