My very first cube, just messing around with the cards that are already owned and getting just a few that I don't that I think would make it fun. I think there's definitely a bit extra graveyard synergy pushing green and red to be a bit weird and different from what I usually hear. But I think it's usually just big enough to where the archetypes don't really force you.
Update code is #.#.# first number will denote major changes in the cube such as entire archetype shifts.
Second number shall be any decently sized chunk of card switching out, for right now I think anything more than 20 cards changing will push the second number.
And that last number will be for any tiny changes I make.
