The main attacker is Calyrex, Suicune is useful against pokemon whose prevent VMAX damage, starmie is a good counter for multiple energy attackers and it has free retrear. Heal damage with Max Potion, and charge your Pokemon with Frosmoth plus capacious bucket or the aqua patchs/Melonies. I know there a lot of good cards in expanded but this list is limited due Sun and Moon Expanded for PTCGL. I hope you enjoy the deck.
