Greninji (Greninja-Ash) @ Choice Specs
Ability: Battle Bond
EVs: 252 SpA / 4 SpD / 252 Spe
- Dark Pulse
- Ice Beam
Ash-Greninja is the main wallbreaker/late game cleaner of the team. When the opponent had been fairly weakened by Mega Scizor or Kartana, Greninja comes in, picks up a fairly easy kill, then transforms and proceeds to sweep. Choice Specs is for extra power, which helps Ash-Greninja break through bulkier Pokemon like Dragonite and Zygarde.
FLOAT DAWG (Landorus-Therian) @ Leftovers
EVs: 252 HP / 252 Atk / 4 SpD
- Stealth Rock
- Knock Off
Landorus-T I chose as the Stealth Rock setter of the team, because it's fairly bulky and also has a really high base attack (145? Uber!) meaning that Earthquake, U-Turn, and Knock Off will do considerable amounts of damage. Leftovers was chosen for gradual healing, and I'm running max HP to take more hits.
Tapuchinno (Tapu Lele) @ Life Orb
Ability: Psychic Surge
EVs: 248 HP / 252 SpA / 8 SpD
- Hidden Power [Fire]
- Shadow Ball
Tapu Lele is my dedicated answer to Mega Scizor, which would otherwise cause problems for the team (Ash-Greninja and Latias), and is able to set up Psychic Terrain to stop opposing Bullet Punches and Extreme Speeds.
X-Scizor (Scizor-Mega) (M) @ Scizorite
EVs: 248 HP / 252 Atk / 8 SpD
- Bullet Punch
- Swords Dance
I chose Mega Scizor as my Mega Evolution on the team because it can do two things: form a TurnTurn pivot core with Landorus-T, and then use powerful Bullet Punches to weaken opposing Pokemon for an Ash-Greninja sweep. It also covers for and resists Grass-type attacks that could hurt Greninja and shorten its sweep.
AeroSoul (Latias) @ Soul Dew
EVs: 252 HP / 252 Def / 4 SpA
- Dragon Pulse
Latias is the Defogger of the team, and can come in, remove hazards, and then Roost up to remove more hazards or switch for the next time they are set. Dragon Pulse and Psyshock are STAB and Soul Dew boosted, but I'm not entirely sure about this set as it gets completely walled by Ferrothorn, so any pointers would be appreciated.
PaperCut (Kartana) @ Fightinium Z
Ability: Beast Boost
EVs: 252 Atk / 4 SpD / 252 Spe
- Sacred Sword
- Smart Strike
- Leaf Blade
- Swords Dance
Kartana is the Fightinium Z variant, and comes in, uses its Z move and then gets a Beast Boost. Leaf Blade and Smart Strike are STAB, and Swords Dance I threw on to boost up even more on Physical Attackers and sweep more.
And pointers on the Latias would be welcome, but it must have Roost and Defog.
