What it does
Volt Switch generates momentum while threatening damage and allows it to exit safely.
Why it's threatening
Rotom-Wash is one of the hardest Pokémon to cleanly KO in the format — it threatens back against almost every common meta Pokémon and Volt Switch means you never have to stay into a bad matchup. Burns cripple
How to stop it
Grass moves are the single clean answer — Rotom-Wash is 2× weak to Grass (its Water typing is weak; Electric is neutral to Grass). A Grass attacker like Venusaur or Meowscarada threatens an OHKO. Don't try to out-damage it with Water or Electric moves; get a Grass type on the field.
