Experimental cube. I forget which podcast I heard it on, but one of the hosts mentioned the possibility of building a cube from just adding all the cards from a full cycle of Commander precons. So that's what I started with, Commander 2021 (Strixhaven), removed duplicates, and added some based on what I thought could be strengthened.

Intended for 4-player draft pod and multiplayer play.

Intended themes:
Red/White artifacts
Blue/Red big spells
Green/Blue +1/+1 counters
White/Black politics
Black/Green life manipulation
