This is actually a really cool idea, though. I've begun building a few cubes before and given up because of the incredibly overwhelming number of options. This is a great way to just start somewhere. Nothing saying you can't start adding other blocks in one at a time later, either.

That's a great point. Although doubling is statistically too much, we can revise the numbers to give a much more accurate representation. I'd done it this eway to keep it relatively simple, but having laid a foundation here there's no reason I can't revisit it and go a bit deeper in that direction. I'll make this part of the next article, thanks for the comment!

In this Standard environment, I think that would be a grave mistake. The two blocks are built around…artifacts and lands. I think that you should, in this case, double that section if possible, cutting each of the other sections down slightly to compensate.
