I attended a Modern Masters draft on Sunday (pulled a Cruel Ultimatum!). During our game, my opponent asked what formats I liked. “Cube!” I exclaimed. We chatted a little about Cube, then he asked “Where do you get your card lists?”
I get this question a lot, and it always surprises me and my answer surprises the asker: me!
I share my lists here, obviously, and you can go to CubeTutor and find all sorts of card lists. But a big appeal of Cube is the ability to make whatever you want.
So I think about what I would like to see. I have a background in literature and history, so I draw upon that. What stories or events do I like?
Or for other people, focus on the types of mechanics you like, or would be fun to play with.
