I have sand tomb on my sandile and I'm just wondering if it would work against elesa's switching strategy
also another question, if volt switch has no effect on the target does it still switch?
The user will not be switched out if the user is the only Pokémon in the party that is able to battle, if Volt Switch fails to hit the target, if the opponent is not affected by Volt Switch, if Volt Switch triggers an opponent's Wimp Out or Emergency Exit, or if using Volt Switch ends the battle.

The target can still switch out if it is holding Shed Shell or uses Baton Pass, U-Turn or Volt Switch.
Hope I helped!
