Hippowdon handles Sandstorm and front-line management, while Mega Dragonite and Mega Meganium look for physical and special sweeps respectively, in this balance build. Greninja's flexible typing and Basculegion/Kingambit's closing power sustain the late game. With an even spread across Water/Ground/Ghost/Steel, there's little risk of the whole team folding to any single type.
Hippowdon (Sitrus Berry): A leading physical wall that sets Sandstorm while clearing the front with Earthquake and Spikes-line pressure.
Greninja (Focus Sash): A versatile attacker whose Protean shifts its type to match the situation for broad matchup coverage, with Focus Sash guaranteeing it survives one hit.
Mega Meganium (Meganiumite): A sustained firepower source with Grass-type STAB and recovery options, dealing steady damage on top of the front line Hippowdon establishes.
Dragonite (Lum Berry): A dual Dragon/Flying STAB ace candidate whose broad coverage lands reliable damage, with Lum Berry letting it endure one more hit to unleash its power at the decisive moment.
Basculegion (Kasib Berry): A dual Water/Ghost resistance rear attacker whose Kasib Berry safely absorbs a Water-type check, staying in the back until it can switch in at an advantageous moment.
Kingambit: A physical closer with a Dark/Steel combo whose Black Glasses-style Dark STAB power is boosted.
