This is a 360 card custom Neon Kamigawa set cube.

I have attempted to balance the color pairs based on a combination of my own extensive experience of playing the NEO retail draft experience and 17 lands statistical data that indicate is the weakest color. In general, there are up to 3 copies of certain commons, up to 2 copies of certain uncommons, and up to 1 copy of each rare or mythic. Several cards are excluded from this cube altogether.
