So, I decided, on a whim - what if I made a cube with only two colors in it? This, so far, is the result. I was trying to see if I could put together a cube that robustly supported multiple UG draft archetypes - counters, enchantments, artifacts/cookies/clues, self-mill, and snow, to mention a few. It's as always a work in progress, but I tried to include enough interaction and green and blue's weird removal to make things interesting! I chose to make it a desert cube because I thought it'd be interesting to have to draft your mana base here.
When playtesting this, please ensure you select 4 packs - it is meant to be drafted as 4 packs of fifteen!
