You can evolve this Pokémon into any other Electric Pokémon on your deck or in your discard pile or you can evolve a Pokémon into Sticker Pikachu in order to evolve it into a different Electric Pokémon (you can only use this card 3 times per game). You cannot evolve your Sticker Pokémon into a Single Strike, Rapid Strike or Fusion Strike Pokémon unless your Sticker Pokémon is also one of those.
