(Edit) Not exactly like “double”. More like TyranitarTube’s Extreme Randomizers. You have to train for a Loooooong time just for a gym.
this is very bad idea
isn’t that basically impossible? it really makes no sense to add
If your pokemon were lvl 120, then they would be 240? also, insane grinding. and they would be unbeatable. the only way to win is to have cheap candies from reborn so that there’s only a 1 level difference. EV train you mons, level them up for good moves, then get lvl 1 mons.
