Ultra Necrozma-GX

Discard all basic Psychic Energy from this Pokémon. This attack does 80 more damage for each card you discarded in this way.

You can use this attack only if the total of both players' remaining Prize cards is 6 or less. Put 6 damage counters on each of your opponent's Pokémon. (You can't use more than 1 GX attack in a game.)
