Team 1's Arbok does not have Shed Skin or Rest, and chose Earthquake as coverage. Misdreavus delights in this fact and checks Arbok because of it. With 216 in speed Misdreavus outspeeds this Arbok and can burn with Will-O-Wisp, which is compounded as an extremely safe option in noting that all Arbok can do is go for either a resisted Gunk Shot that does 1/4 at +1 after the burn or a Sucker Punch that won't even work. Other options include setting up a Nasty Plot directly in Arbok's face or going for the raw Shadow Ball/Nasty Plot expecting a switch. Arbok's only hope of getting past this Misdreavus is by wearing it down slowly with Gunk Shot on the switch-in 3-6 times and begging for the poison.
Beyond checking Arbok really well, Misdreavus also has decent synergy with Piloswine. Piloswine is weak to Fighting, and Misdreavus is immune to Fighting. Piloswine can set up Stealth Rock, and Misdreavus appreciates hazards to grab some 0HKOs. Piloswine is weak to Water, and Misdreavus can have Thunderbolt to KO those pesky Waters. Piloswine is a physical attacker with hazards and bulk, and Misdreavus is a special attacker with setup and bulk. Even pokes that could theoretically take on both, such as Machoke, can be worn down easily by the natural bulk and power that both have.
With both Pokemon on Team 2, Team 1 will have to get creative.
