name: Scarfpert
move 1: Waterfall/Aqua Tail
move 2: Ice punch
move 3: Earthquake
move 4: Stone Edge
item: Choice scarf
nature: Jolly
evs: 4 hp/252atk/252spe
Why this set deserves to be on site:
This set is great for revenge killing. It outspeeds Dragonite after a single dragon dance and will ohko it with ice punch after stealth rock damage (non bulky will be a ohko). Earthquake will destroy any Heatran not holding a shuca berry. Both waterfall and earthquake ohko any Infernape. A -1 ice punch will still 2hko salamence while living an outrage. Stone edge will 2hko any togekiss. Being immune to thunderwave is a big help to swampert in its ability to revenge kill.
Teemates/counters:
This set works well with and gets walled by scizor. Scizor can absorb grass attacks aimed at swampert but an opposing will take all momentum this swampert has and throw it out the window. Salamence/Dragonite also work well because the share good synergy. Scizor can lure in a fire attack and this swampert will most likely be able to take the hit very well and get a hit off itself.
Additional comments:
You could use brick break/hammer arm/superpower to hit tyranitar for a 2hko every time.(you would probobly switch after using it so hammer arm is still viable.) superpower will always ohko a standard tyranitar.
