Forbidden Deck

Forbidden Deck is an adult card-battling adventure game where players explore a map, challenge rivals, and collect character cards called Muses to build custom decks. The core gameplay revolves around strategic card duels: win booster packs from opponents, upgrade your cards across multiple levels, and assemble a powerful deck to face increasingly challenging rivals. The game features a tutorial, quick-play matches, a deck editor, and an unlockable gallery. All characters are adults.
