***HORDE RULES***
- Any choice The Horde must make should be made as randomly as possible.
- "Target player" is the active player.
- The Horde has unlimited mana of every colour.
- Activated abilities may only be activated by the Horde once per card.
- All creatures controlled by The Horde have Haste and "This creature must attack each turn if able."
- The Horde has no life total. Damage dealt to The Horde causes that many cards from the top of The Horde's library to be put into its graveyard.

Zombie Horde Rules

- Deck composition: 50 cards (6-10 Enchantments, Sorceries, or Instants, 34-40 Zombie or Zombie-related creature cards), plus 50 Zombie tokens.
- The Survivors win when all Zombies in play are dead, and the Zombie Horde deck has been depleted.
- The Zombie Horde draws cards from the top of its deck until it draws a non-token card. All tokens drawn are put into play, and the non-token card is cast for free.
- When the Zombie Horde "gains life," put a number of the bottom cards of their graveyard under their library equal to the amount of life gained.
- Any time a card effect required the Horde to put a token into play, this doesn't count towards the deck limit; those tokens are exiled as normal when killed, instead of placed in the Horde Graveyard.
- Returning a permanent card to the Horde's "hand" will result in the card being cast for free at the Horde's next turn.
- If the Horde must exile cards of any specific type from the graveyard, they are exiled first from the top.

Specific Rules

Diregraf Colossus
 - When Diregraf Colossus is drawn, if there are fewer than 3 zombie creature cards and tokens in The Horde's Graveyard, put it on the bottom of the Horde deck and draw another card. If a token is drawn in its place, the draw continues.
 - Zombie Tokens count for the first ability.
 - "Zombie Spells" are zombie creature cards with mana costs, even if the Horde doesn't pay them. Zombie tokens "cast" from the Horde deck do not count.

Unbreathing Horde
 - Zombie tokens count.

Sutured Ghoul
 - Zombie tokens count for the exiling ability.
 - When Sutured Ghoul is drawn, if there are fewer than 3 zombie creature cards and tokens in The Horde's Graveyard, put it on the bottom of the Horde deck and draw another card. If a token is drawn in its place, the draw continues.
 - Sutured Ghoul exiles the topmost cards of the Horde's graveyard in no particular order. The maximum number of cards to be exiled is 10 per player in the Survivor role. Cards with a variable power (such as the Noosegraf Mob, Soulless One, or another Sutured Ghoul) are worth 0.

***HARD MODE***
Replace all 5 enchantments in the regular deck with copies of Open the Graves, and the Horde deck begins with a permanent copy of Endless Ranks of the Dead in play.
