Another Sun-Steel format deck (cards from Sun & Moon on are legal - Banlist includes Acerola, Bellelba & Brycen Man, Marshadow, Mismagius, & Oranguru). So many BIG DAMAGE Charizard cards exist! If only Water didn't exist as well *sobs*. Welder is pretty awesome. You CAN play Magma Basin for extra acceleration, but so far Giant Hearth plus Welder gets the job done. That said, theoretically you can Flare Strike turn 1 with this deck combination. Just a few Jirachi and one Dedenne GX to help you dig early and fast. Deck is fun; try it out!
