10th Edition+M10+M11+SOM+M12+ISD+M13+RTR+M14 Cube

Now, this is a much more affordable idea. All of these sets are either black border core sets or have recently rotated out of Standard; or will rotate out of this format by this October. This selection has 15 sets. It is one block and one core set larger than the largest Standard format. Only three of these sets (Mirrodin Besieged, New Phyrexia, and Dark Ascension) are small sets. Bounding a cube makes the experience a lot more fun. Otherwise, you eventually wind up dragging in every card ever printed. These are the selections I plan to build to, each in its own fat pack box that fits 300 sleeved cards:

1. Infect (1 box, 300 cards).
2. Artifacts (4 boxes, 1200 cards).
3. Tribals (5 boxes, 1500 cards). I have already built one of these as UB (Blue Black) Zombies. The other candidates are Humans and Angels (White), Vampires (Red Black), Goblins (Red) and Elves (Green).
4. Guilds of Ravnica (10 boxes, 3000 cards). Another alternative is to build to the five shards (Bant, Esper, Grixis, Naya, Jund) and use 5 boxes instead....that's only 1500 cards.

That's 20 fat pack boxes, 6000 cards or 4500 cards if we stick to shards for the RTR-themed selections. Most of these cards will be commons and uncommons, and that means that the sleeves will be worth as much as the cards, but I am a casual player, and why not! This cube will be missing many of the more expensive cards, and that is OK. I don't have the budget to pimp up one of these cubes.
