This cube is inspired by, though not limited to, my favorite plane in the Multiverse. I fell in love with Ravnica, and that has inspired the creation of this cube. There is only 1 novel component to this cube: each player begins each game with a Pillar of the Paruns on the battlefield. This is important to know this as you draft, so that you aren't nearly as concerned about mana fixing as you might otherwise be. Additionally, it is worth pointing out that Pillars does not work for activated abilities, so plan accordingly :)
This is a labor of love for me, and I hope that you enjoy it! Let me know if you have questions about cards I have included or cards you think are worth putting in it; I will be tinkering with it pretty significantly in the next few weeks and would love some input!
