Greiger's Decks

Greiger plays a Reactor/Burn Deck. His monsters are based on World War II-style aircraft and inflicts damage to his opponent whenever a specific type of card is played. Once Greiger becomes one of the Dark Signers he recieved "Earthbound Immortal Chacu Challhua" and his Deck was supplemented with monsters based upon naval or undersea craft in addition to his Reactors.

In Yu-Gi-Oh! 5D's Stardust Accelerator, Greiger uses a Turbo Deck, focusing on the "Reactor" monsters, called "Card Bomb! Boom!"
