A Theros-themed cube with a twist: Rather than playing AGAINST the other drafters, players will be organized into teams to play against the Hydra, Horde, or Xenagos collectively. Packs 2 and 3 are seeded to each contain a Hero's path card, of which players are allowed to use up to 2 in the final confrontation. This will be a prototype for another cube built around horde magic with no theme limit.
