I can think of… five Duelists who would count as FIRE Duelists off the top of my head. Six if you want to be generous.

The newest pack “Duelist Pack: Duelist of Explosion” includes cards used by Duelists from the anime and manga, and is confirmed for release on May 27th, 2023. This booster pack is designed to supercharge the Decks of Duelists who use FIRE monsters, souping up their Decks with brand new cards.
