Gardevoir @ Gardevoirite
Ability: Trace
EVs: 24 Def / 232 SpA / 252 Spe
Modest Nature
- Hyper Voice
- Psyshock
- Focus Blast
- Calm Mind
Mega Gardevoir hits extremely hard with its main stab Hyper Voice not too many mons can come in safely. Psyshock hits Venusaur which OHKOs it after a Calm Mind. Focus Blast is to hit steel types if you wanna risk it.
Keldeo @ Choice Scarf
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hydro Pump
- Scald
- Icy Wind
- Secret Sword
Keldeo compliments Gardevoir pretty well as Gardevoir can handle the Lati twins and destroy their souls with a Hyper Voice. Whereas Keldeo can do the same to steel types like Heatran and Ferrothorn. Icy Wind can hit the Latis on the switch and will make Gardevoir faster than them. Keld also serves as a decent Bisharp check who would otherwise destroy Gardevoir with a Sucker Punch. The scarf is for extra speed since this team is pretty slow.
Bisharp @ Life Orb
Ability: Defiant
EVs: 72 HP / 252 Atk / 184 Spe
Adamant Nature
- Sword Dance
- Sucker Punch
- Iron Head
- Knock Off
A great SD sweeper who can pressure mons to not defog. Bisharp serves as a secondary switch into Latios who might go for Psyshock on the predicted Gardevoir and if Bish can come in safely Bisharp will wreck the other team. Life Orb is for that extra power, but Lum Berry is also a good option since this team has no status absorbers.
Landorus-Therian (M) @ Leftovers
Ability: Intimidate
EVs: 244 HP / 4 Atk / 252 Def / 8 Spe
Impish Nature
- U-turn
- Earthquake
- Stone Edge
- Stealth Rock
Lando-T is for getting up rocks and checking strong physical attackers such as Charizard-X and Talonflame. The rocks also pressures the opponent to go for defog which can end up really good for Bisharp as it gets a from SD for just coming in.
Tentacruel @ Black Sludge
Ability: Liquid Ooze
EVs: 224 HP / 252 Def / 32 Spe
Bold Nature
- Scald
- Rapid Spin
- Acid Spray
- Knock Off
This team had no switch-ins to Keldeo as well as no way of getting rid of hazards so I went with Tentacruel who handles both jobs. Scald for the potential burn, Acid Spray is to handle CM Clef, and Knock Off helps a lot as well. With the defensive EVs Tentacruel can take Brave Birds from Talon, Knock Off from Bisharp, and even a Psyshock from Latias should they decide stay in.
"Hi!" Rotom coming in on a scald and not getting burned :]
Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 252 HP / 212 SpD / 44 Spe
Calm Nature
- Will-O-Wisp
- Hydro Pump
- Volt Switch
- Pain Split
Another issue for this team was Volt Switching which Sdef Rotom-W handles pretty well. Rotom tends to have a good match-up against other teams so it doesn't mind getting Volt Switched on as much. Rotom also serves as a secondary check to bird spam as well as Keldeo and other strong special attacks. Though Rotom isn't a tank so shouldn't be brought it on extremely powerful special attacks like M-Gardevoir's Hyper Voice.
Summary: A great team with a lot of offensive pressure from both Keldeo and Gardevoir while the rest support them pretty well. I don't see too many flaws atm besides the defensive core of Rotom/Lando/Tenta gets worn down easily. Any ideas on how to make this team stronger will be much appreciated thanks~ <3
