Hello! 
I'm currently right before the Kanto elite 4, and I'm trying to level up some strong pokemon.  
I'm aware of the false swipe method, and I've gotten my false swiper to a high level, but I'm having some trouble.   
I can't farm with pokemon that do not have priority moves. I will leave the wild pokemon at 1 hp, let my swiper die, bring out the pokemon I want to exp, but it will get one shot by the wild Pokemon because it is so slow and will attack second.   
Are there any priority move tutors in Kanto? I can not use daycare or enter cerulean cave yet.   
Is there an alternative way to farm exp?
