Mawile's Intimidate and Hippowdon's Sandstorm/Stealth Rock clean up the front, while Mega Floette and Heat Rotom maximize late-game special firepower with Nasty Plot lines. Greninja's Protean widens its matchup coverage. Carrying two Nasty Plot-line attackers on both the physical and special side means the team's firepower doesn't die even if the cycle gets interrupted.
Mega Mawile (Intimidate): Play Rough / Knock Off / Sucker Punch / Brick Break. Lowers the opponent's physical line with Intimidate before pressuring with Sucker Punch priority as the lead.
Hippowdon (Sitrus Berry, Sand Stream): Earthquake / Stealth Rock / Yawn / Whirlwind. Handles the front with a Stealth Rock and Yawn cycle, slowly grinding the opponent down.
Garchomp (Choice Scarf, Rough Skin): Earthquake / Outrage / Rock Slide / Sleep Talk. Uses its Scarf's priority in speed to land high-power Outrage as the closer.
Heat Rotom (Leftovers, Levitate): Overheat / Discharge / Nasty Plot / Substitute. Sets Substitute then boosts Sp. Atk with Nasty Plot to maximize damage as the secondary ace.
Greninja (Life Orb, Protean): Dark Pulse / Ice Beam / Sludge Wave / Water Shuriken. A versatile attacker whose Protean shifts its type to match the situation, creating type-matchup advantages.
Mega Floette (Fairy Aura): Moonblast / Light of Ruin / Psychic / Substitute. Fairy Aura massively boosts its own Fairy-type STAB, making it the team's final special powerhouse.
