Each player discards the top card of his or her deck. This attack does 20 damage plus 20 more damage for each Unown discarded in this way.

Poké-Power PUT

Once during your turn (before your attack), if Unown P is on your Bench, you may put 1 damage counter on 1 of your Pokémon (excluding any Unown).

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