The idea here is that Slugma predicts the switch-in to it, sets up either Reflect or Light Screen, and uses Memento, giving Snover an easy set-up opportunity. Slugma's STAB Fire-type move will deter Pawniard from switching in to absorb Memento, although physical Piplup will be a larger issue. While it is setting up, Slugma tends to draw in Water- and Ground-types, most of which Snover can set up on (be careful of Fire Punch Cubone though), as well as Archen, which Snover can force out with the threat of Ice Shard. Once boosted by a Swords Dance, Snover becomes quite threatening and can attempt a sweep.
Snover's Ice Shard is its priority move, allowing it to pick off weakened threats. Bullet Seed deals heavy damage once boosted, and is its main STAB move against most other Pokemon. Wood Hammer is an option when raw power is needed, but Ice Punch can also be used to deal with Foongus, who is able to avoid the OHKO from +2 Ice Shard.
The given Slugma EVs allow it to survive OHKOs from most attacks while behind either Reflect or Light Screen, giving it the opportunity to Memento, while the Snover EVs allow it to outpace Porygon and Timburr, with the rest dumped into HP after Attack has been maximized so Life Orb and Wood Hammer deal a lower percentage of Snover's health.

As you can see, Choice Scarf Pawniard is not enough to deal with a healthy boosted Snover because Iron Head will not come close to OHKOing, while a combination of a +2 3 hit Bullet Seed and Ice Shard will KO Pawniard after Hail Damage.
Before attempting a sweep, Fire-types and Magnemite should be taken out or weakened to within Ice Shard range; this is easily done with Diglett. In addition, it is best if hazards are cleared, because both Slugma and Snover are weak to Stealth Rock and affected by Spikes and Toxic Spikes.
