The Venniliannes deck is a mixture of a Reptilian Deck with Vennominaga/Vennominon. Another key difference is that this deck allows easy access to summon Vennominaga.
This is my first article so please don't be harsh.
The deck consists of these cards,
Monsters
2X: Oshaleon
3X: Reptilianne Gardna
3X: Reptilianne Gorgon
3X: Reptilianne Naga
3X:Reptilianne Vaskii
2X: Vennominon the King of Poisonous Snakes
2X:Vennominaga the Deity of Poisonous Snakes.
Spells
1X: Allure of Darkness
2X: Mystical Space Typhoon
2X: Pot Of Duality
2X: Trade-In
3X: Viper's Rebirth
3X: Snake Rain
Traps
2X: Defense Draw
2X: Rise of the Snake Deity
1X: Dark Bribe
1-3X: Call of the Haunted
41-43 Cards.
How to use this deck:
-Use Reptilianne Naga and Reptilianne Gorgon to make the opponents strongest monsters have 0 attack.
-Use Snake Rain to send Vennominon to the graveyard.
-You can use Viper's Rebirth to summon Vennominon from your graveyard while you control Rise of the Snake Deity. During the end phase, Vennominon is sent to the graveyard, then activate Rise to the Snake Deity. Snake Rain can also be used to add damage to your Vennominaga the Deity of Poisonous Snakes.
-You can use Call of the Haunted to bring Vennominon from the grave after you already have a Vennominaga the Deity of Poisonous Snakes on the field. Having two Vennominaga the Deity of Poisonous Snakes is just adding insult to injury.
-Dark Bribe should always be used to prevent anything from negating the activation of Rise of the Snake Deity.
