Zombies are one of Magic's deepest creature types, concentrated most heavily in black and blue. Zombie decks excel at graveyard recursion, sacrifice, tokens, and replacing dead creatures with still more dead creatures.
Diregraf Captain strengthens Zombies while draining opponents when they die, Rooftop Storm can reduce Zombie creature spells to zero mana, and Necroduality doubles up all nontoken Zombie creatures you control. Gravecrawler provides one of the most useful recurring bodies for sacrifice engines.
