How Garchomp plays
Garchomp's Ground type plus Earthquake gives spread-damage threat against grounded opponents that pure dragons miss, and Rough Skin punishes contact moves whether Garchomp goes first or second. Speed at base 102 sits above the unboosted Pelipper and Whimsicott tier and below the Tailwind cluster, which means Garchomp lives or dies on speed-control timing.
Most builds run Choice Scarf to lock the speed tier or Loaded Dice with Scale Shot for setup-and-sweep lines. Watch for protect-game decisions: a Choice Scarf Garchomp read and Wide Guard'd into a no-Earthquake turn loses the slot for the rest of the game. The optimal partner is anything that reduces Earthquake's collateral damage on your side, which is why levitating partners and Flying types dominate Garchomp pairings. Wash Rotom is the most common natural fit.
