Drafting:

• 20 card packs, each pack has 2 oathbreakers, pick 2 cards at a time
• Choose a planeswalker you drafted to be your oathbreaker that determines your deck's color identity, as well as an instant or sorcery in that color identity to be your signature spell
• 60 card decks, including oathbreaker and signature spell
• For rules of the oathbreaker format, see: https://oathbreakermtg.org/quick-rules/
• If you have a mono-colored oathbreaker, you may have any mono-colored instant or sorcery as your signature spell. Your deck’s color identity is the colors of both cards
• Similar to The Prismatic Piper in Commander Legends, you may have Karn, Scion of Urza as your oathbreaker. If you do, choose two colors to be your deck’s color identity
• Similarly, You may have Introduction to Prophecy as your signature spell. If you pair it with a mono-colored oathbreaker, choose a second color to add to your deck's color identity
