Let me clarify, just in case.. I said Banette, because its counterpart, Dusclops, got an evolution after RSE.
The only other one from Hoenn this has happened to is, Skarmory not getting a "Mantyke", but Mantine was not found in RSE so it doesn't matter in this case.
Just remembered Roserade <3
Roselias would actually be useful for a Hoenn journey with that!
