What is the Omniscience Draft Cube?
The Omniscience Draft Cube (Omnicube for short) is a 360 card draft cube inspired by the Magic Arena Omniscience draft event format. Players draft a 40 card minimum deck and play best of 5 game rounds with an emblem. The emblem states that a player may play cards from their hand without paying their mana costs. The emblem also has “0: Add WUBRG to your mana pool. Activate this ability only once per turn.”
