Pokémon-GX rule: When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
Abilities, attacks, weakness & resistance
As long as this Pokémon is your Active Pokémon, all of your Pokémon take 30 less damage from your opponent's attacks (after applying Weakness and Resistance).
If there is any Stadium card in play, this attack does 120 more damage. Then, discard that Stadium card.
This attack's damage isn't affected by any effects on your opponent's Active Pokémon. (You can't use more than 1 GX attack in a game.)

Flygon-GX (sm12-218 Holofoil) is a Fighting-type Stage 2 Pokémon-GX from the Cosmic Eclipse set. It has the Dusty Defense Ability, which reduces damage your Pokémon take by 30 while Flygon-GX is Active, and two attacks including Desert Hurricane that can remove a Stadium and Sonic Edge-GX which deals 220 damage and ignores effects on the opponent's Active Pokémon. Its GX status means knockouts award two Prize cards and you can only use one GX attack per game, positioning it as a high-risk, high-reward attacker and stadium answer in decks.
