I've been thinking of doing a run of firered/leafgreen with the weakest fully evolved Pokemon, but I'm not sure what all should be on my team. I'm pretty set on ratticate and farfetch'd, but unfsure who the remaining four should be. Possible shitmon canidates are onix, seaking or kingler (i do need a surf mon after all),flareon, butterfree and beedrill.
Please keep in mind gen 3 meta when suggesting pokemon and always assume the final evolution (not including cross gen evolutions like steelix and kingdra). Even if magikarp sucks garaydos isn't the worst water pokemon.
