The Vow Destroyer Cube. Its concerned about creating a commander draft like experience, instead playing 1v1 using an oath-breaker and a signature spell.

RULES:
Players draft three packs of 20 cards, choosing two cards per pack and attempting to make a 60 card deck.

Players attempt to draft around planeswalkers and a signature spell. If a player does not draft a planeswalker, they may choose an uncommon planeswalker not yet drafted and place it into their draft pile. If they do not draft an instant or sorcery within a planeswalkers colour identity (see next rule), they may choose a colourless instant or sorcery with the subtype 'Lesson' and put it into their draft pile.

When deck building, a deck must conform to an oathbreakers colour identity. If that oathbreaker is a monocoloured card, they may add one more colour into that oathbreakers colour identity, for as long as the signature spell chosen is that colour.

Players start with thirty life and no draw if your on the play.
