Diancie-Mega @ Diancite
Ability: Magic Bounce
EVs: 16 Atk / 240 SpA / 252 Spe
Naive Nature
- Moonblast
- Earth Power
- Protect
- Diamond Storm
First off, I wanted to use Mega Diancie because it is very powerful, has decent offenses, and has a degree of unpredictability in which set and moves it has. I chose Protect for this particular set in order to get its 110 speed in its Mega form much easier. The 16 Atk evs are to OHKO Zapdos with Diamond Storm.
I chose Earth Power for its ability to hit Excadrill and Heatran hard over Hidden Power Fire. Moonblast and Diamond Storm are just its 2 reliable, powerful STABS.
Talonflame @ Sharp Beak
Ability: Gale Wings
EVs: 88 HP / 252 Atk / 168 Spe
Jolly Nature
- Swords Dance
- Brave Bird
- Flare Blitz
- Roost
Next, I chose Talonflame because it kills many things that give Diancie trouble, such as Scizor, Skarmory, Mega Venusaur, Amoonguss, Clefable and Ferrothorn. This set is Swords Dance because it makes for a great sweeper after Diancie eliminates or weakens its counters, like Tyranitar. Speed evs are to outspeed max speed Raikou.
Celebi @ Leftovers
Ability: Natural Cure
EVs: 252 HP / 4 SpA / 252 Spe
Timid Nature
IVs: NaN Atk
- Giga Drain
- Nasty Plot
- Baton Pass
- Recover
Third, I chose Celebi for a few reasons. One, its typing and bulk allow it to be a solid answer to most water types, like Manaphy and Keldeo and also checking Mega Diancie. It has access to Nasty Pass so it can allow Mega Diancie, Latias ,Keldeo, and itself to easily put a dent into the opponent's team. The final reason is the fact that Baton Bass itself prevents itself from becoming complete Pursuit bait from the likes of Bisharp. All around, a solid mon.
Keldeo-Resolute @ Choice Scarf
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hydro Pump
- Scald
- Secret Sword
- Hidden Power [Electric]
Now here the monster known as Keldeo. I used it because I could've used reliable checks to Mamoswine, Landorus (both forms), M-Lopunny, and Bisharp. Also, the combination of Nasty Pass+ Scarf Keldeo makes for a great late game sweeper once all the checks and counters are weakened/dead.
Landorus-Therian (M) @ Leftovers
Ability: Intimidate
EVs: 252 HP / 240 Def / 8 SpD / 8 Spe
Impish Nature
- Stealth Rock
- Earthquake
- U-turn
- Knock Off
With Landorus, I needed a reliable SR setter, bird spam check, M-Lopunny check, and Excadrill check. It is able to do all this while providing momentum with U-turn and hitting hard with Earthquake. It serves as a nice all-around poke.
Latias (F) @ Life Orb
Ability: Levitate
EVs: 72 HP / 184 SpA / 252 Spe
Timid Nature
IVs: NaN Atk
- Draco Meteor
- Psyshock
- Defog
- Healing Wish
With the last slot, I needed a good hazard remover that also was a reliable Electric check, another Keldeo check, and something that could provide status healing. Latias fits the bill while doing respectable damage with its STABS and having a solid 110 speed tier.
What I noticed about it is that Gyarados and Thundurus are annoying pokes, but keeping Keldeo and Latias healthy for them works most of the time.
