Unown [H]

Once during your turn (before your attack), if you have Unown [H], Unown [E], Unown [L], and Unown [P] on your Bench, you may shuffle your hand into your deck, then draw a new hand of the same number of cards.

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.
