Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
This guy's been cleaning up pretty much all my matches lately:
Arbok @ Black Sludge
Ability: Shed Skin
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Coil
- Gunk Shot
- Sucker Punch
- Seed Bomb
One of the absolute joys of Scalemons (and truly any alternative meta) is the ability to let lowly Pokemon that are dear to you shine and regain the element of surprise. Here's a set I've been running and looooving:
Stunfisk @ Assault Vest
Ability: Static
EVs: 252 HP / 4 Def / 252 SpA...
Mega Swampert still has value in other applications. A Sap Sipper set will almost always invite an unwitting attack boost. Z-Tailwind + STAB Bonemerang and Crabhammer pretty much guarantee massive crits, and w/ the speed boost and Icicle Crash can deal w/ Garchomp.
Mega-Beedrill is one of many pokemon that breaks Inverse and is idiot-proof, but I've found that any Sturdy pokemon w/ decent offense is pretty much guaranteed to OHKO it. My Donphan has prompted many a rage quit.
I think the two most reliable Tapu Koko switch-ins I've employed thus far are Mantine and Motor Drive Electevire.
Mantine is comfortably bulky and has a 4x resistance, Electevire can absorb an electric move and actually have some offensive utility, especially after a speed boost from Motor Drive.
Been having success w/ this on a Rain Dance team
Armaldo @ Rocky Helmet/ Leftovers
Ability: Swift Swim
EVs: 248 Atk/ 8 SpD/ 252 Spe
Adamant Nature
-Aqua Tail
-Stone Edge
-X-Scissor
-Hone Claws
usually knocks out Tapu Koko, Aqua Tail hits grass types expecting to switch into X-Scissor
