I'm doing a nuzlocke and beat up to misty with no casualties and the team I'm rolling with right who are all also at the level cap are Wartortle, Pidgeoto, Raticate, Beedrill(best bug type by far), Gloom and Golbat.
Also this is a hardcore nuzlocke where I can only use Pokemon who have bst of more than 300 and have a bst less/equal too 500.
If I had got Geodude in Mt. Moon It would have been easy but luck was not on my side and got a zubat who I allowed because it evolves into golbat that is viable but didn't use it else where in any major battles only wild Pokemon battle to train up same as pidgeoto and raticate.
The other 2 gyms brock and misty were easy but lt.surge is bad as three are weak to it, 1 resists,one is neutral and the other is ok.
How can I beat him with less causalties?
