GX Moves And Game Mechanics

GX attacks function as attacks that you may use only once per game if you control the GX card with the attack.

GX attacks use the same attack timing as regular attacks if you have the required energy attached.

GX attacks end when they resolve if they cause a knockout or a game state change.

GX attacks override normal damage limits if the attack text specifies higher damage.

GX attacks do not stack if multiple GX cards are in play because the game rule allows one GX use per player per game.

GX counters do not reset between turns unless a card effect specifically states otherwise.
