there's a lot of shitty sets in this thread so here's a few really good ones:
Ludicolo @ Life Orb
Ability: Swift Swim
Shiny: Yes (blue Ludi is best Ludi)
EVs: 252 Spd / 252 SAtk / 4 HP
Modest Nature
- Rain Dance
- Hydro Pump
- Giga Drain
- Ice Beam
Ludicolo causes a lot of switches so it's really easy to get up a Rain Dance, and when that happens your opponent is in for four turns of absolute hell. One of the scariest sweepers in this tier, your opponent is gonna need a strong special wall in order to not get completely demolished. This set is meant to function as a standalone sweeper which is why I'd take Life Orb over Damp Rock.
Dragonair @ Eviolite
Ability: Marvel Scale
Shiny: Yes (if you're not using pink Dragonair we can't be friends)
EVs: 252 HP / 4 Atk / 252 SDef
Careful Nature
- Rest
- Sleep Talk
- Dragon Dance/Thunder Wave/Toxic
- Outrage/Dragon Tail
Tanks special hits like you wouldn't believe, but Marvel Scale is what takes this set to the next level. While RestTalking, you have one of the most potent mixed walls in NU. You can take the set in two completely different directions though based on your style or what you want for your team: you can go for the Dragon Dance sweep (obviously boned by fairies), or you can go for phazing with your status of choice. Just a really strong, underrated set no matter what moves you pick.
Sigilyph @ Life Orb
Ability: Magic Guard
Shiny: Yes (green Sigi best Sigi)
EVs: 252 HP / 252 SAtk / 4 SDef or 4 HP / 252 SAtk / 252 Spd
Modest Nature
- Ice Beam/Dazzling Gleam/Energy Ball/Air Slash
- Psychic/Psyshock
- Heat Wave
- Roost
This is the best Sigilyph set, not those gimmicky Cosmic Power sets that lose to anyone smart enough to carry Taunt. You can either take advantage of Sigi's solid base 97 speed or go for the bulkier set, personally I almost always go for the bulkier option but you could probably come in the middle to beat a certain threat that you have in mind if you're better at EVs than I am. Sigilyph has an excellent offensive movepool that gives you a ton of options based on what you need it to kill. Heat Wave and Roost are mandatory, but the first slot can go to all kinds of things. Each option is good in it's own right so it basically comes down to preference and team needs.
Primeape (M) @ Choice Scarf
Ability: Vital Spirit
Shiny: Yes (duh)
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature
- Close Combat
- Punishment/Ice Punch
- U-turn
- Stone Edge/Ice Punch
It's ridiculous how much this guy does for teams. Being able to outspeed +1 Venomoth/Vivillion, being immune to sleep, and being able to OHKO both with Stone Edge makes this guy one of the tier's best at handling those pests. Additionally Punishment absolutely destroys Cosmic Power Sigilyph, so if you have issues with him you have a bit of a panic button at the ready. I believe I got the idea for Punishment from Destiny by the way, so props to her. Ice Punch is extremely useful on him but it's hard to fit in a slot since Stone Edge is so important in this bug/flying/fire oriented meta. I guess you could forego U-turn but it's such a great momentum move and works so well that I think it should be pretty much required.
And now for a set that's pretty obvious but is
seriously excellent:
Qwilfish @ Leftovers
Ability: Intimidate
Shiny: Yes (again, if you're not using pink Qwilfish you don't deserve to win ever again)
EVs: 252 Def / 252 HP / 4 Atk
Impish Nature
- Spikes
- Waterfall/Aqua Jet
- Thunder Wave/Toxic Spikes/Toxic
- Taunt/Pain Split/Haze
The best defensive spike setter in the tier (I won't argue it's merits over Accelgor which is probably more inherently reliable). I hope everyone's aware that Intimidate is one of the best abilities in Pokemon, especially in a tier with a stupid amount of strong set-up sweepers or crazy cannons like Archeops. Physical attacks just plain tickle this guy, and he can retaliate in a lot of ways, by setting up Spikes for your team and getting things paralyzed. You can take Toxic Spikes too but that's a lot of hazards to rely on one Pokemon for. Taunt is almost definitely the best option in the last slot, letting you screw over all kinds of things that like to come in on Qwilfish and set up. Pain Split and Haze are also good options, but not quite as good as Taunt I'd say.
