Decision to complete this was based on timing.
(returning from road trip around the south, likely not being around friend with whom I play Magic within 2-3 years)

But mostly I finished it due to boredom and restlessness.

Initially had leaned against doing this project due to time cost, relatively low satisfaction, and to a lesser extent money. In all, took less time than I expected.

Have completed at this point. Played a few times in various iterations with my friend, only in one-on-one drafts. Likely to have future tweaks as we play more, but I think thing work relatively well.
I found this cube ultimately satisfying to make, a lot of unique interactions with cards not typically used, and also a relatively original concept.
