How do you catch electivire in Pokemon white 2?

In Pokémon White 2, Electivire cannot be caught in the wild, as it is not available in the game's encounter tables. Instead, you can obtain Electivire by evolving an Electabuzz. To do this, trade an Electabuzz holding an Electirizer, which is an item that triggers its evolution into Electivire when traded. You can find Electabuzz in the wild in the Chargestone Cave or through trading with other players.
