ok. so. first off, we need to synergize this team. so here are my humble suggestions:
Dragonite @ Leftovers
Trait: Multiscale
Jolly Nature
EVs: 252 Spe/ 212 Atk/ 44 HP
- Outrage
- ExtremeSpeed
- Superpower/Earthquake
- Roost/Aqua Tail
Standard TankNite set. offers optimal coverage for OU.
Swampert @ Leftovers
Trait: Torrent
Adamant Nature
EVs: 252 Atk/ 252 HP/ 4 SDef
- Waterfall
- Curse
- Earthquake
- Hammer Arm/Stealth Rock
Curse Sweeper. since Spe will be lower than an anorexic model's sense of self worth, Hammer Arm doesn't really have any drawbacks. Stealth Rock is IF you lack EH support with other members but i will get to that later.
Espeon @ Lum Berry
Trait: Magic Bounce
Timid Nature
EVs: 252 Spe/ 252 HP/ 4 Def
- Heal Bell
- Wish
- Psychic
- Detect
Support. Magic Bounce will reflect status and entry hazards. Heal Bell cures status from your whole team, and Detect is for trolling.
Electrode? ewww!! use Rotom-W!!
Rotom-Wash @ Choice Scarf
Trait: Levitate
Modest Nature
EVs: 252 SAtk/ 252 HP/ 4 Def
- Thunderbolt
- Trick
- Hydro Pump
- Volt Switch
TrickScarf set. locks opponent into an awful move and forces them to switch and prevents setup or recovery.
I suggest Alakazam over Gardevoir.
Alakazam @ Life Orb
Trait: Magic Guard
Timid Nature
EVs: 252 Spe/ 252 SAtk/ 4 HP
- Psyshock/Psychic
- Focus Blast
- Hidden Power Ice/Thunderbolt
- Grass Knot/Shadow Ball
Magic Orb abuser. 30% Boost to attacks with no Life Orb recoil? sign me up.
Blissey @ Leftovers
Trait: Natural Cure
Calm Nature
EVs: 252 HP/ 252 SDef/ 4 Def
- Stealth Rock/Toxic
- Seismic Toss
- Protect
- Wish/Softboiled
Stall Wall. easy to use, easy to abuse.
hope this helps :)
