(Assuming this CCAT is continued): So far, we have SD Lickilicky, which is arguably old meta given Bouffalant dropped since the time this started (although, Lickilicky does have things like Knock Off / Power Whip / Explosion / can't be taunted out of SD over Bouff), Scarf Chatot, and Probopass. Right now, it's looking to shape up to be a pretty decent Normal spam team, but still needs a few things like a wallbreaker and something to beat Ghosts, particularly Misdreavus and Gourgeist-Super for Bouffalant, an answer to offensive Water-types like Simipour and Floatzel, a general stop to offensive Ice-types like Rotom-F and RP Regice, and a few checks to Fighting-types given it's a Normal spam team.
So, I'm gonna start with that wallbreaker slot:
Stoutland @ Choice Band
Ability: Scrappy
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Facade
- Frustration
- Superpower
- Crunch
Why Stoutland? It's an easy switch-in to Misdreavus, wallbreaks for Bouffalant, and can generally wreak havoc on teams once your Probopass has trapped opposing Steel types. Why Jolly? You can actually bait Adamant Monferno into attacking you with Close Combat, only to be outsped and OHKO'd by Jolly Frustration / Facade if Stoutland has been statused. With Monferno being baited (although not guaranteed because it can also run Jolly), Probopass and Bouffalant will have a much easier time doing what they do. Finally, I think Crunch is much more useful than Pursuit here, as that lets you hit Solrock and Metang pretty hard, given that Solrock walls Bouffalant, and Stoutland is walled by Metang without it. Removing either Metang or Solrock is pretty important on a Normal Spam team like this one.
Another pokemon that'd be fine for this slot would be Guts Machoke, as that also takes on Misdreavus comfortably and can break down Tangela with Knock Off / breaks down physically defensive Rock-types like Relicanth with its Fighting STAB, while also resisting its Head Smash.
Once this wallbreaker slot has been decided on, I'd probably go and use something like Grumpig as a check to Fighting-types, and a much needed answer to things like RP Regice. Grumpig can also threaten Ghost-types with its own Shadow Ball, while also being able to slow things down with Thunder Wave for slower Pokemon like Bouffalant.
