Here is your Piloswine team
pokemonisfun!
Rest Talk Piloswine is a beast offensively with solid defensive utility, its STABs hit harder than Nidoqueen's Earthquake/Ice Beam, noticeably letting it comfortably 3HKO Hypno without any support. It also doesn't come with a pesky Psychic or Ice weakness, making it far more suitable at checking Electabuzz and Haunter. There are a couple of issues you definitely have to be wary of when using and building with it however, the biggest ones being that Fire Blast is by far the more common standard on Nidoqueen, and that Piloswine is a bit of an unreliable Scyther check as once it's asleep its unlikely to pull a move that can actually threaten it.
This team revolves around using Piloswine as a threatening early-to-mid game wallbreaker in conjunction with Spikes and Thief support. Curse Qwilfish is used to keep Spikes up reliably against Blastoise, which is definitely one of your better Piloswine checks. Thief + Hidden Power Electric Omastar gives you a normal resist that can remove the items from Piloswine checks like Blastoise and Slowbro; HP Electric is useful to dissuade Qwilfish trying to take the Thief in particular, and stops Gyarados switching in on you freely.
Hypno gives you a nice Mr. Mime and Nidoqueen check, and provides insane value to your Piloswine by letting it stay in against targets like Slowking to pressure them even heavier if Light Screen is up. Light Screen also lets you more aggressively bring Piloswine in on Mr. Mime so that you don't need to play Hypno stalemates with it. Jumpluff gives you a much needed solid primary Scyther answer alongside Piloswine and Omastar and back-up Granbull answer due to no Rest on Omastar, its double powder support is very useful here too in letting Piloswine outspeed threats like Qwilfish and Nidoqueen.
Granbull rounds out the team with a nice additional breaker and win condition, and way of pressuring targets like Rest Gyarados that would otherwise endlessly harass your team and heal off all their damage while burning sleep turns against Piloswine and Hypno. Thunder is used over Sleep Talk here as a neat way of breaking through Omastar - in particular if Spikes are up, you can 2HKO Omastar on switch-in with a paralysis on the first Thunder, removing Granbulls biggest Counter. The rest of the team appreciates this as otherwise your Hypno will be forced to defensively check it and potentially pick up a burn. It also hits Haunter still and lets Piloswine / Hypno take it out without even needing to take an Explosion if it lands a paralysis on them.
Granbull likes the Light Screen support here to better pressure Slowtwins / Ampharos. Rest without Sleep Talk is manageable here as Scyther / Nidoqueen are solidly covered by other members of the team, and you can try to burn sleep turns with Light Screen up against special attackers like Mime / Hypno / Slowtwins.

Hope you enjoy the team!
