Whenever I try to start a battle with someone, after setting the rules and all that, when I click ok it tells me I can't participate. The "Special Pokemon: Permitted" is red and it says "You don't meet the conditions, so you cannot participate". When I select "info" it brings up two boxes on the top screen. Party pokemon says banned twice but doesn't say what is banned. Same thing with the battle box, but there is nothing in it. How do I fix this?
My party is:
Ferroseed, Lv. 32 @ Leftovers
Tyrantrum, Lv. 55 @ Leftovers
Swampert, Lv. 39 @ Nothing
Aegislash, Lv. 51 @ Nothing
Blaziken, Lv. 36 @ Blazikenite
Gengar, Lv. 67 @ Gengarite.
If it matters, all these pokemon were traded over from pokemon Y.
