I most liked Kaldheim. After snow lands were starting to picked appropriately, it felt like a very balanced and complex format. I also love any format where aggro is really viable. Koma was **** though.
Strixhaven had some good elements, but although learning was neat, the best Lessons being colorless and there being really only two main archetypes (WB aggro and GUR ramp) made drafting feel samey.
MID was very fun to play game-wise but blue being so strong was hard. That said, like I said, I really liked drafting red aggro while everyone was doing zombies. I did not enjoy AFR or VOW.
I was just telling a friend that it did feel like drafting went into a slump after several good years.
