>>33010749I'm doing the same kind of run in Yellow, only using guys I've never used before.
So far I've got Raticate, Venomoth, and Ponyta, all mons I've never used. I can honestly say Venomoth has been surprisingly powerful, but since you're avoiding Poison-types, try Kangaskhan for a Normal. He's one I plan to use.
Any anons wanna suggest me a Pokémon off this small list of the Gen 1 mons I have left to take for a spin?
