Is this for Sun/Moon? Do they have illegal move tutor moves? Since there are only certain ones available in Sun/Moon.
It's for Ultra moon but they both give problems on moon as well cuz I just transferred them over for a few minutes to see.
Unless someone, somehow, for some reason took my game and changed them with whatever you use for that (is it still the game shark/action replay?!) they're completely legit caught and trained by myself.
Their movesets are as simple as they come:
Absol has protect, superpower (which I thought in Ultra moon at battle tree), night slash and psycho cut.
Gardevoir has hypervoice (battle frontier ORAS) thunderbolt, psychic and shadow ball.
Gardevoir does have a contest memory ribbon which I thought might be the problem but that still doesn't solve Absol because she doesn't have that and sadly enough I can't backtransfer her cuz ribbons are kind of important for me XD
