What is the best approach to beating LT. Surge in Pokémon Ash Grey?
Solution 1:
Status Effects and a lot of luck.
I've watched several videos now of this particular fight. Most involve a status effect and stalling your goddamn heart out. One used poison (after savescumming to get a fight where Raichu's first attack missed Bulbasaur), one used Leech Seed (similarly), and two used paralysis (a level 30 Pikachu might apparently take down Raichu in two Thundershocks and a Quick Attack). Most of these take some degree of luck to still wear the big mouse down, though. Arceus be with you!
