You can erase one Pokémon from ever existing, but you have to replace it with a new one

Which Pokémon would you erase from existing and what would you replace it with. Don't need a name, just what the Pokémon is based on and typing.
I'd get rid of Luvdisc and replace it with a Dolphin Pokémon with a Water/Steel typing.
