Zombie Deck

There are a few main concepts for a Zombie Deck. One focuses on swarming the field with Zombies, usually from the Graveyard, and the other is milling your opponent's deck out.

Zombie Mill Deck
This kind of deck is best mixed with other types of mill decks for best results. Cards that work well in the deck are Vampire Lord, Vampire Lady, Soul-Absorbing Bone Tower, Malice Ascendant, Robbin' Zombie, Gravekeeper's Servant, Needle Worm, ect. A powerful strategy is having three Bone Towers and suiciding Pyramid Turtle (or having it as defense, as Bone Tower cannot be taken out when Pyramid Turtle is out), taking out 18 cards from the Deck, almost half the Deck.

Zombie Swarm Deck
This kind of deck focuses on Special summoning Zombies, especially from the Graveyard. Pyramid Turtle searches out most of your Zombies, while Zombie Master, Il Blud, and Book of Life reuse the effect of Pyramid Turtle. Card Trooper and Magical Merchant helps get monsters in your graveyard for them. Card of Safe Return is obvious in this deck, since it works very well with Premature Burial, Call of the Haunted, Monster Reborn, Book of Life, Zombie Master, Il Blud, and Vampire Lord. Also, since many high attack monsters can be special summoned quickly, Deck Devastation Virus becomes a useful card in this deck.
