This cube was designed to teach cube drafting to my children. The themes are simple and it's full of the cards they like best--planeswalkers and flashy dragons. Since I love the AFR set, I constructed it exclusively from those cards. The themes and color balance are adjusted somewhat from the AFR retail draft experience to keep it more interesting for me. I also included some fun "build around" cards like Tiamat and the Vecna cards to allow for a more challenging draft experience when I'm playing against my kids.
