So yeah, here's my attempt at a stall team.
@ Eviolite
Ability: Natural Cure
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
- Heal Bell
- Wish
- Protect
- Seismic Toss
Pretty basic Chansey set. Wish+Protect allows self-heals and wastes turns, allowing some of the other things on the team to do their thing. Heal Bell alleviates the fact that the team is somewhat weak to burn, and Seismic Toss is taken over Toxic since other things are already spreading status.
@ Leftovers
Ability: Sturdy
EVs: 252 HP / 4 Def / 252 SpD
Impish Nature
- Whirlwind
- Spikes
- Roost
- Drill Peck
Full Sp.D investment with Impish nature maxes out stat boosts and allows Skarmory to take special hits (usually a Rotom-W Volt Switch) if needed. Spikes is taken over SR because Heatran sets rocks, and Drill Peck has no recoil.
@ Rocky Helmet
Ability: Iron Barbs
EVs: 248 HP / 8 Atk / 252 Def
Relaxed Nature
IVs: 0 Spe
- Leech Seed
- Gyro Ball
- Toxic
- Protect
Toxic something, Leech Seed it, and force tons of switches, allowing hazard damage to rack up. Protect wastes turns, and Rocky Helmet can allow for surprise eliminations of physical attackers such as Talonflame that have already set up, though this often results in Ferrothorn's loss.
@ Air Balloon
Ability: Flash Fire
EVs: 248 HP / 8 SpA / 252 SpD
Calm Nature
- Lava Plume
- Stealth Rock
- Protect
- Will-O-Wisp
Compensates for the HUGE fire weakness on the team, sets rocks, and neuters most physical attackers. Pretty standard set, not much to say.
@ Leftovers
Ability: Sturdy
EVs: 252 HP / 4 Def / 252 SpD
Impish Nature
- Volt Switch
- Rapid Spin
- Toxic Spikes
- Explosion/Stealth Rock
@ 334nite
Ability: Natural Cure
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Return
- Dragon Dance
- Roost
- Substitute
A somewhat bulky sweeper to round out the team and provide endgame cleaning. Pixilate Return hits absurdly hard, and Substitute+Roost ensure that it is difficult to revenge kill.
Too much steel, I know.
