I find Skorupi to be criminally underused these days. It has great bulk, an expansive movepool, a decentish typing, and just enough of everything else to matter.
Here's a set that works wonders in the current metagame, and often catches people off-guard in the process.
Skorupi @ Eviolite
EVs: 240 Atk / 36 Def / 76 SDef / 156 Spd
Adamant Nature (+Atk, -SAtk)
- Toxic Spikes
- Knock Off
- Cross Poison
- Brick Break
Sort of a weird set, but I'll explain. 156 Spd puts you at 15 speed, allowing you to outspeed Mienfoo and Knock Off its Eviolite with ease, making it that much easier to kill. And while we're on the subject of Mienfoo, Skorupi walls it completely. Most (over) used pokemon in the tier? Check (but more so counter). Max out attack to hit hard, and the rest of the points are dumped to increase its defenses a little. Toxic Spikes is wonderfully useful, and Skorupi does an admirable job at setting them up, arguably the best in the tier. Like I said before, Knock Off screws over Mienfoo, and anyone else that runs Eviolite (which is every pokemon in the bloody tier). I can't tell you how much utility Knock Off has in LC. It wins games.
For attacks, we have Cross Poison for good, reliable STAB, and Sniper is also really cool when it activates. Brick Break is fairly unorthodox, but it works surprisingly well. It allows you to reliably hit a ton of stuff for super-effective damage, allowing you to 2HKO Magnemite and 3HKO bulkier mons like Ferroseed and Munchlax. You do get walled by Ghost types and Croagunk, but it's not like X-Scissor handles those any better.
