Its main attack, and it should be noted that VMAX Pokemon can use their main attacks as many times per match as needed, is called G-Max Wildfire
However, theres a specific breakdown of each card type and how many to include because of their use in the game most decks include around 15 Pokemon cards, 30 Trainer cards, and 15 Energy cards
