>>31858150It depends. For example, Raichu, Marowak, Exeggutor, Sandslash, Muk and Ninetales are unusable in their normal forms at least in this format.
Although you could argue that's because movepools, stats, and types are different from one to another, there's this inflexibility in terms of what is from Alola and what isn't. That anon is basically asking some "borderline" question, since that Gastrodon serves no advantage to the other form aside from the color he should be able to use the pink one, however I think it might be banned due to GF's inflexibility as I said.
I was surprised they at least allow egg moves that can be bred through bankmons so at least we have that.
