This is the Battle the Horde deck for the Born of the Gods game day event. These aren't the actual cards but I've found functional copies to use. Ignore the mana cost and simply cast two each turn.
Artifacts:
All Artifacts (and enchantments but they count as artifacts while in play) have "At the beginning of the Horde's precombat main phase, reveal an additional card from the top of the Horde's library. The Horde casts that card." When the artifact goes to the greaveyard do the effect listed on the actual card.
When Millstone leaves the battlefield, the Horde deck mills 7 cards.
When Tooth and Claw leaves the battlefield, the Horde deck sacrifices two minotaurs.
Incite War also gives attacking creatures "must be blocked this turn if able."
Path of Anger's Flame also adds "sacrifice attacking creatures at end of combat."
Ready / Willing just gives attacking creatures deathtouch until end of turn.
Lightning Elemental also dies at end of turn.
Apes of Rath enter the battlefield tapped but untap normally.
All creatures have "~ attacks each turn if able."
