update

bubble strat is dead, although I would imagine there are brighter minds than my own working out a new "confusion" strat for power leveling friendly gyms.

If you want to do the bubblestrat, try using a (lv 1.5) diglett with mudslap as your attacker and as a defender get either a raichu or electrode with volt switch at 11 hp(lv 1), IVs are more flexible on the raichu than electrode due to raichu having a lower Defense stat, its going to be hard to do so i would recommond making a new low leveled account so that you can try to get these combonations
