Unown H

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

Poke-POWER — HEAL: Once during your turn (before your attack), if you have Unown H, Unown E, Unown A, and Unown L on your Bench, you may remove all Special Conditions from 1 of your Active Pokémon.

Hidden Power (30): Discard a card from your hand. (If you can't discard a card from your hand, this attack does nothing.)
