Though the Pokmon TCG Scarlet & Violet expansion is set to officially release on March 31st, players have been able to get their hands on cards earlier by competing in friendly tournaments at Play Pokmon stores using a series of pre-built decks

This release is themed around Mega Charizard X, but will also feature Diancie and Gengar's mega forms
