>>28416643Do interesting playthroughs.
For example, after doing a mono-pure-water playthrough in X, I became bros with Basculin and Alomomola. After a normal-type run in FireRed, I liked Clefable. A Nuzlocke run can also serve this purpose well, but I haven't actually taken one to completion yet.

>>28416738 also helps. Try replaying a game, but don't use any of the six 'mons you used the first time around.
In general, though, keep an open mind. I thought Octillery was pretty meh, but I decided to use one when I wasn't sure what else to add to my Gold team. It ended up being bro-tier against Claire and the E4. Good Surf user, too.
>>28416728Klefki is cool, largely because of the lore behind it. Ignore the haters.
>>28416841Therian Lando would actually be kinda cool if it weren't attached to Incarnate Lando, so I'll give you a pass on this one.
