Tired of Ground-types ruining your Volt Switching fun? Now you can do something about them! It does seem gimmicky, but there's more to simply removing their immunity to Electric simply to allow unpunished Volt Switches. Note that Ring Target only removes immunities regarding typing, so immunities via abilities still remain.
Most Rotom switch-ins have at least one immunity, even if it's not Electric. Shedding that immunity gives your fellow sweepers an easier time spamming moves. An unsuspecting Golurk now finds itself helpless before Sawk's CB Close Combat. Bulky Normal-types such as Licklicky or Miltank dislike losing their Leftovers and being susceptible to Shadow Balls. All of a sudden, Seismitoad is staring down an Electric weakness as opposed to an immunity. A Skuntank looking to trap/revenge kill you risks being exposed to Psychic moves and Toxic, and that's just the tip of the iceberg of what you could do by stripping a target of its immunity and item.
Rotom could run Substitute to usher its usual checks/counters to switch in. The health lost can be regained with Leftovers if you managed to steal them. Thunderbolt can be used to take on the Ground-type Rotom check right there and is a strong Electric move that doesn't force you out.
Rotom-Fan lures Ground types better due to the lack of super effective STAB that destroys them, allowing you to Trick them and Volt Switch away (another Electric-type as a partner is recommended); Rotom-Frost on the other hand isn't as bothered by Lightningrod/Motor Drive pokemon as much as its couterpart, and can use this set to turn the tables on its greatest counter, Piloswine by robbing it of not just its immunity, but also its Eviolite, which you can quickly dispatch of it with Thunderbolt right after.
