>>22644691Help him in two ways, first make few NU/RU or whatever tier the shit he wants teams are so you he can run his favorite shit. You don't have to go full autism pentaperfect; 3IVs or 4IVs would work well enough because your only goal is have fun with your friend.
Secondly, make him a few core IV/EV bred UU and OU guys. Since you already have 5iv motherfuckers kicking around, you can give him some breeding stock and team cores so you aren't forced to play his one stupid team over and over again.
Actually there is a third way which is play some of the super retarded formats like mixed tiers (No more than 2 OU, 2 UU, and 2RU/NU), monotype, color teams, little cup et cetera.
