In this cube I've elected to not include cards with a CMC higher than 4, for the reason that i wanted intense games in which the
correct play wasn't so obvious and your cards had a similar enough CMC that you'd have a lot of choices for what to play instead
of running out a smooth curve. It's mostly modern cards but ignoring some bannings while also having some non-modern legal cards
where either the color combination needed it(Shardless Agent) or the card would fulfill a vital function(Price of Progress). Also
ABURs because i dislike having a low life total because of my lands. The Cube of course has a very Modern feel to its play.
