Unown [G]

Once during your turn (before your attack), if you have Unown [G], Unown [I], Unown [V], and Unown [E] on your Bench, you may flip a coin. If heads, search your deck for a basic Energy card and attach it to 1 of your Pokémon. Shuffle your deck afterward.

You may have up to 4 Basic Pokémon cards in your deck with Unown in their names.

It is believed that the variety of types of this Pokémon were created by evolutionary adaptation, as each possesses a different ability.
