# Battle Deck

A battle deck is a customizable team of pets that players can set up in the game to battle in [Eternians mode](/eternals_world/gomoku/game-modes.md#eternians-mode). Each pet belongs to a specific race with unique specialized skills, and players can coordinate these skills to create powerful combinations. To start building a pet deck, players must own Eternals NFTs, which unlock the ability to assemble and manage their team of pets.
