Professor Viper's Decks

Anime
Viper plays a "Venom" Deck which is themed on the distribution of "Venom Counters" through his monsters such as "Venom Snake" and "Venom Boa" to an opponent's monsters as means of weakening and ultimately destroying them. Several of his monsters are based on the nāga, a serpent-like race in Hindu and Buddhist mythology. One of these creatures, Viper's signature card "Vennominaga the Deity of Poisonous Snakes", is able to circulate poison in the opponent's body upon inflicting damage, declaring an automatic victory for its owner within three turns.
