>>48043200Espeon with Psybeam and Bite covers over half of the GSC E4’s Pokémon. Ampharos (with Fire Punch for Koga’s Forretress), Feraligatr, and Jynx cover just about everything else. I think I kept Heracross with Rock Smash on the team just for Karen’s Umbreon. I used Crobat with Mean Look and Confuse Ray to catch the dogs relatively easily after getting Fly.
>>48043431Acquiring Crobat early is kinda grindy, but it’s optional, and grinding for one friendship evo isn’t the same as grinding a whole team for the E4 or Red.
