Virus Control Deck

A Virus Control Deck is not usually seen outside Japan, for the pure reason that although both of the key cards needed have been released in English, one of them "Crush Card Virus" is exceptionally rare in the TCG.

A Virus Control Deck focuses around these 3 Trap Cards:
 * Crush Card Virus
 * Deck Devastation Virus
 * Eradicator Epidemic Virus

Crush Card Virus needs a Dark monster with 1000 ATK or less, while Deck Devastation Virus needs a Dark monster with 2000 ATK or more, and Eradicator Epidemic Virus needs monsters with 2500 ATK or more. Suitable cards include:

Dark 1000 ATK or Below

 * Dark Scorpion - Meanae the Thorn
 * Destiny Hero - Defender
 * Destiny Hero - Fear Monger
 * Destiny Hero - Malicious
 * Giant Germ
 * Mask of Darkness
 * Old Vindictive Magician
 * Plague Wolf
 * Sangan
 * Spirit Reaper
 * Peten the Dark Clown

Dark 2000 ATK or Above

 * Axe Dragonute
 * Chaos Sorcerer (Traditional only)
 * Destiny Hero - Dasher
 * Giant Orc
 * Goldd, Wu-Lord of Dark World
 * Gravekeeper's Assailant and Gravekeeper's Spear Soldier with Necrovalley
 * Helpoemer
 * Infernal Dragon
 * Mist Archfiend
 * Plague Wolf: This card can be boosted to 2000 ATK by its own effect.
 * Ryu Kokki
 * Sillva, Warlord of Dark World
 * Swift Gaia the Fierce Knight
 * The Fiend Megacyber
 * Vampire Lord
 * Zombyra the Dark

Dark 2500 ATK or Above

 * Vampire's Curse
 * Dark Magician
 * Dark Magician of Chaos
 * Fusilier Dragon, the Dual-Mode Beast
 * Messenger of Hades - Gors
 * Summoned Skull
 * Cyberdark Horn: This card can boosted to 2500 Atk if equipped with Hunter Dragon
 * Cyberdark Edge: This card can boosted to 2500 Atk if equipped with Hunter Dragon
 * Cyberdark Keel: This card can boosted to 2500 Atk if equipped with Hunter Dragon

Cards that lower/raise ATK will also make it able to be used, if the ATK requirements are not met. For example, Vorse Raider has 1900 ATK points. Equipped with Black Pendant, it can be used with Deck Devastation Virus, and if it has Shrink used on it, it can be used with Crush Card Virus. The use of Mystic Plasma Zone enables a variety of monsters to be used with "Eradicator Epidemic Virus". Similarly, Mucus Yolk, Plague Wolf, and Prometheus, King of the Shadows can raise their ATK with their own effects, thus allowing them to fulfill the requirement for almost any of the three Virus traps at any time.
