Unown I

Pokémon

Basic — Psychic

Poke-POWER: ITEM

Once during your turn (before your attack), if you have Unown I, Unown T, Unown E, and Unown M on your Bench, you may search your deck for a Trainer card, show it to your opponent, and put it into your hand. Shuffle your deck afterward. You can't use more than 1 ITEM Poké-Power each turn.

Hidden Power (Colorless)

Choose an Energy card attached to the Defending Pokémon and put it face down. Treat that card as a Special Energy card that provides Colorless Energy and doesn't have any effect other than providing Energy. Put that card face up at the end of your opponent's next turn.

HP 50

Weakness Psychic +10

Retreat 1

Shaped like ancient writing, it is a huge mystery whether language or UNOWN came first.
