When you're dealing with black magic, necromancers - those who can summon and command the undead - come with the territory. Liliana Vess is one of the most powerful ones, and this deck shows off some of her favourite minions: zombies.
For one thing, zombies like to kill things. Creatures like "Black Cat" and "Fleshbag Marauder" can force your opponent to discard cards or sacrifice their creatures, while creatures with "first strike" or "deathtouch" can sometimes destroy opposing creatures regardless of how strong they are.
"Doom Blade" and "Tendrils of Corruption" will let you take the slaughter into your own hands if your horde of corpses needs a bit of help.
For another thing, zombies don't like staying dead. "Gravecrawler", "Bloodghast", "Butcher Ghoul", and "veilborn Ghoul" all have ways of rising out of your graveyard and shambling back into your hand or onto the battlefield.
"Cruel Revival" brings a "zombie" creature back to your hand from the graveyard while destroying an opposing creature, and "Grim Return" can revive a creature that was sent to the graveyard during the same turn to fight for you again... even if it belongs to your opponent!
Finally, where there's one zombie, there are usually more. "Liliana's Reaver", "Grave Titan", and "Endless Ranks of the Dead" can create "zombie" creature tokens, allowing you to bury your opponent under an avalanche of cadavers!
