So Gothita wasn't an awful replacement for Gardevoir. Gardevoir may be stronger in the long run, but Gothita's Competitive is wrecking all the early game debuff-abusing mons.
i don't think competitive will have much use in-game really. And shadow tag either. I have rarely seen a gym leader switch their pkm while it's still alive. But Frisk would be nice if you want to hunt wild pokemon with items :v
