Strixhaven Set cube. It tries to keep the ration of commons/uncommons pretty close to a normal booster. Main changes include cutting many of the unplayables and non-draft focused cards, then replacing them with cards aimed at boosting the archetypes that didn't quite fire in the set (Lorehold synergy and counters especially, but I also added some lands/fixing to make wedge archetypes more playable). The Mystical Archive cards are the biggest difference between this and the set as printed, I added a completely different set of them, they tend to be higher power and more synergistic, or often cards that I think will just be fun. It's the easiest thing to change in the cube.
