Pit Fighter: Fantasy Arena is a multi mechanic game. It combines the maneuverability of a miniatures game, the money management of a European board game, and the meta-game of a CCG. While we say CCG, that isn’t quite true. To control the action of your character in the Pit, you create a deck, exactly like you would a CCG, but the cards available for Pit Fighter: Fantasy Arena are not randomized and have no rarity. The starter box comes with 2 sets of Expansion pack #1. You can purchase extra expansion packs, currently 3 of them are available. Each Expansion has pre-set cards, so you know exactly what cards you get when you purchase the Expansion Pack. Each Expansion pack has 21 cards in it, and the cover tells you what cards the pack has.
