It's a set cube. No more, no less.

My distribution is 3/2/1 among Commons, Uncommons and Rare/Mythic Rare).

The only variation I have from this rule is: If there is an AltArt card (aka Showcase), then there will be a full set of the AltArts in the Cube.
Example 1: 2 Ogre-Head Helm (Rare Card with an AltArt, so two in summary)
Example 2: 6 Jukai (3 regular, 3 AltArt)

It pans out pretty well just by looking at the numbers. I am curious what happens, when a specific card is more then 3/2/1 times in the cube and if it affect's gameplay or archetypes. :)

Disclaimer: I'm counting the five different Hidetsugo AltArt as one variation. If I get my hands on one of them, that counts. Otherwise it's a money sink. :D
Same goes for borderless/bordered cards, that depicts the same artwork. I just want pretty pictures, not all the cards. ^^
