I started a new playthrough in Yellow a while back and beat Surge. I used the Mew Glitch to get a Gengar, but I don't know if I should bother with it. There's so much more drawbacks to it than there were in later gens, so I figured I'd just stick with using Venusaur & Nidoking for poison and Mew for Psychic. Should I stick with it or leave it boxed?
