Serpentis Duel

Master a card duel inspired by snakes. Battle the CPU with ATK/DEF, Moon and Thunder fields, and two fusion recipes.

King Cobra gains +500 ATK against Serpents. Black Mamba strikes first when defending in ATK, and all Elapids paralyze their opponent for two turns.

Danger mode adds 300 snake species, from venomous to nonvenomous, in five game tiers. Search names or families, choose any species and face the CPU with same-tier decks. Tiers are game values, not a scientific scale of toxicity or human risk. Classic duels retain eight cards including Coral Snake, Jararaca, Boa and Anaconda.
