Here's an overlooked Pokemon for your perusal: Pancham! I haven't seen it around all that much while battling, so I assumed it wasn't all that great. I ended up being wrong, as it's not all that bad of a Pokemon. I still legitimately don't know what to do with it, however, so I'll try to piece something together for you all right here, right now.
Best Ability: Scrappy.
Self-explanatory, really. Scrappy allows Pancham's best moves to work on Ghost-types, and even gives Pancham's Fighting-type moves super effective coverage on Honedge, one of LC's rising stars.
Notice that this list is a short one. Turns out that Pancham, unlike its evolution, doesn't have any nifty coverage moves like Poison Jab or Earthquake to take advantage of. The standout moves here are the ones that could really make Pancham a handy bulky Pokemon to have around, like Circle Throw and Parting Shot. The latter is especially noticeable, as it allows Pancham to decrease offensive stats and maintain momentum, and it's a very spammable move. With these moves glossed over, it's time for some sets that optimize Pancham's unique movepool.
Pancham @ Berry Juice / Eviolite
EVs: I'm not good with EV spreads, so I'll find something later.
-Bulk Up / Parting Shot
This set is untested, but I feel like it could be very useful in the long run. My issue with Pancham mainly springs from its lack of survivability and susceptibility to status, and using a RestTalk strategy remedies this. I'd prefer Parting Shot on this set, because it allows me to avoid potential threats while messing with their stats, so that I can force more switches later on. Ideally, this set should be used with heavy hazard support from Dwebble or something like that, mainly because of the switch-forcing that you want to happen. Bulk Up is okay as well, but reliance on it makes it easier to encore Pancham or phaze it out. I like Pancham best when he's slipping through your fingers with double phazing moves.

Pancham @ Choice Scarf
EVs: Once again, I'll work this out later.
My second set relies on a fast Parting Shot as a means to get other Pokemon into battle safely. That way, neither Pancham or any teammate has to take that much damage on the switch. With a little bit of prediction, this set can excel in the metagame (don't worry, I have tested this one). Circle Throw is a spammable move that can get you out of a bind with slower offensive sweepers like certain Misdreavus and Gligar, and can be used with impunity. Shadow Claw ruins weakened Ghost and Psychic-types, though a Fighting-type move of choice is equally good in some cases thanks to Scrappy. Though you can always use Circle Throw here, Storm Throw has a higher damage output, prevents the opponent from coming back and setting up again, and doesn't have negative priority, a serious burden to any Scarfer. Jolly nature is necessary to outspeed some threats, so I put it over Adamant.
This concludes the first Pancham-related thread on the forum. Please give me feedback on these sets, tell me which one is better (I prefer RestTalk so far), and please help me with the EV spreads so that I can actually use Pancham in the LC metagame. I believe that it's worth it.
