I am trying to play in Random Matchup but it says "There was a problem with your Pokemon, and they could not participate." then it disconnects from Wi-Fi. my Pokemon that I am trying to use is:
Gallade Lv.100 Pokerus
Swampert Lv.100 also has Gift Ribbon
Salamence Lv.100 (Shiny)
Garchomp Lv.100 (Shiny)
None of them have Sky Drop or Dark Void
None of my Pokemon have the same item and I got Salamence and Swampert from trade and Garchomp and Gallade on the GTS.
Please help me as fast as you can because I'm trying to enter a tournament that is in 3 days.
I just tried out random matchup without my Swampert and replaced it with a Yanma and it worked so it must be the Swampert, but why?
