The team
Kyurem-Black @ Choice Specs
Ability: Teravolt
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Hidden Power [Fire]
- Draco Meteor
- Ice Beam
- Earth Power
So I wanted to use specs Kyurem-Black. It throws many people off guard, One it Koing Rotom-W, Mega Venusaur and Skarmory using teravolt, all which can be a problem for Mega Diancie. Hidden power fire One hit Ko'es Scizor and put Ferrothorn in range of Diancie. Ice beam is a hard hitting stab move I can throw off on Hippo, Defensive Lando-T and Tank Chomp.
Diancie @ Diancite
Ability: Clear Body
EVs: 8 Atk / 248 SpA / 252 Spe
Naive Nature
- Moonblast
- Diamond Storm
- Earth Power
- Protect
Mega Diancie is a great partner for specs Kyurem, as Kyurem can get rid of many of its counters such as Ferrothorn, Scizor, and Skarmory. Mega Diancie in turn checks Mega Sableye and can clean up late game once pokemon such as Rotom-W and Defensive Lando-T and Hippo are weakened or out of the way.
Latios @ Life Orb
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Hasty Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Draco Meteor
- Psyshock
- Hidden Power [Fire]
- Defog
Specs Kyurem needed hazard control. Latios fit the role perfectly as it was another way to get rid of Scizor and Ferrothorn and can switch into Keldeo and Zard Y, both of which were looking like big threats until now.
Landorus-Therian @ Rocky Helmet
Ability: Intimidate
EVs: 248 HP / 244 Def / 8 SpD / 8 Spe
Impish Nature
- Stealth Rock
- U-turn
- Earthquake
- Stone Edge
DD zard X with EQ was looking to be a problem, so what mon to switch in than Defensive Lando-T. I still needed a stealth rocker and It can switch into talon flame if I don't want Diancie to get weakened. U-Turn also allows me to get initiative into my heavy hitters such as specs Kyurem and Diancie.
Keldeo-Resolute @ Choice Scarf
Ability: Justified
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Scald
- Secret Sword
- Hydro Pump
- Icy Wind
Weavile was also looking to be a problem until now, and scarf keldeo both switches in and outspeeds. Chansey also looked to be an issue but Secret sword 2 hit ko'es it. Bisharp also looked to be a threat, as it destroys the entire team with Sucker punch at +2 if Diancie gets weakened, so Keldeo also switches in to SD Bisharp.
Jirachi @ Choice Scarf
Ability: Serene Grace
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Iron Head
- U-turn
- Fire Punch
- Healing Wish
I wanted a steel type to support my dragons, and scarf Jirachi seemed perfect. The team was 6-0'ed by Serperior until I added this pokemon. It also acted as a clefable killer, putting it in range for Diancie to clean up. It also checks Mega Diancie, which if it wins some speed ties really puts holes in the team.
The only big problems that I found were the occasional Calm Mind Mega Slowbro and Crocune, but I don't run into them very often and if I play offensive with U-Turn I usually don't allow them to set up. Thank you for reading and if you have any tips I would love to hear them :].
