Making a few changes, mostly to add newer cards that have been released in Wilds of Eldraine, Lost Caverns of Ixalan, and Murders at Karlov Manor. Some of the changes are strict upgrades (Confounding Riddle over Supreme Will), others are major power level upgrades (apologies to Spitebellows and Aethersnipe; I love you both dearly but 17 years of power creep is really starting to catch up to you), and others are just to replace cards that never get maindecked (Lithoform Engine).
I do like a lot of the off-color Adventure creatures, but I'll have to think more about how the color ramifications work before figuring out how many of them I want to add, if any.
First major round of changes I've made to the Cube in a while. Essentially I'm just replacing some of the cards that never seemed to make maindecks, or never seemed to get drafted at all. Added in a couple new March of the Machine cards that seemed like solid fits (particularly Invasion of New Phyrexia) and a couple older cards I missed (honestly how did I overlook Kenrith; it's got five activated abilities lmao). Added a couple more low drops for white and red aggro as well.
