Ability: Sand Rush
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Earthquake
- Iron Head
- Rapid Spin

Assault vest for extra special defensive bulk. Rapid spin for some switch in set up teams, iron head for fairy and stab move, earthquake ad strong stab move. Rock slide for flying and bug killer.

Sola (Volcarona) @ Focus Sash

EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature

Special attack God, quiver dance for buffs, focus sash to ensure one will be used, bugg buzz for dark and psychic and grass types. Gigs drain for health regeneration, and Water, ground, and rock. Fiery dance for moderately powerful special attack buff potential fire type move.

Ability: Thick Fat
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature

Main lead, counters most teams. Rotom Pokemon are trouble. Good against almost everything. Assault vest for special attack fire types. Combine it with thick fat fire is almost nullified.

Thank you for evaluation.

Comments

Garchomp: Iron head already covers ice. Replace rock slide with swords dance.
Alakazam: Replace shock wave with focus blast. Water and flying types aren't really a threat, but dark types are.
Cresselia: Replace chesto berry with leftovers because you won't always encounter spore users. Calm mind already offers SpD boost, so instead max out HP and Def and replace modest with impish. This would make it a pure stall set. It's much more reliable than an offensive set, especially since it can just stall, max out calm mind, and then sweep. If you want shorter battles, however, don't change nature or EV spread.
Excadrill: Replace assault vest with life orb. Fast sweepers like Excadrill don't need SpD. Since you aren't setting up a sandstorm, replace sand rush with mold breaker.
Otherwise, pretty good team.

Rock Slide can be used over Iron Head for EdgeQuake coverage. Generally used to cover more pokemon over the spectrum. Iron Head is more of faires than Ice types anyway.

but the only Pokemon that a dragon/ground/steel combo can't hit for regular damage are Skarmory and Bronzong. Both rely on contact moves to deal damage, so they shouldn't be much of a problem to Garchomp. Swords dance is still better.
