I was wondering, for people who are interested in these Universes Beyond commander decks, I wonder if you got all 4 decks and took out all the basics, duplicate cards, and cards that require being in a commander game to play (command tower for example), how close would that be to making a cube out of those decks?
Like, looking at the Dr. Who decks, if you took out most of that stuff you still have around 300 cards. So you could definitely use some of those slots to fill in mana curves and adjust mana fixing, and I bet you could make a fun and flavorful cube out of any if these UB commander sets you enjoy!
I dunno, just a thought!
