the Draft

• sleeve the module in a sleeve color different from your cube
• get 120 cube cards and 60 Horde cards, shuffle them into one pile
• grid draft this pile, with you picking first every time
• add all Horde cards undrafted by you to the Horde deck

You should end up with a horde deck of 30-50 cards; this will be your opponent. Balancing is a strategic choice in the draft: problem cards can be drafted away.

Solo Gameplay

The Horde acts as a normal opponent, but has no starting hand size and no life total. You are the starting player, starting at 7 cards (before muligans) and 20 life.

• the Horde casts 1 random card from their hand in each main phase, without paying its mana cost
• Horde creatures will attack their opponent if able
• Horde creatures won't block if able
• whenever the Horde loses life, they mill that many cards
• whenever the Horde gains life, shuffle that many random cards from their graveyard into their library
• if the Horde would draw a card from an empty library, you win the game
• all choices for the Horde are randomized

Two Headed Giant

Instead of grid-drafting the cube, take 120 cards from your cube as a sealed pool for both players. The Zombie Horde will use their entire 60-card deck. Use the two-headed giant rules for the players (30 life, shared phases). The Horde is the starting player.
