I posted a new micro-format on my website!

Inspired by the ultra-budget cube I made, this Commander variant only allows cards that cost 10 cents or less. Which means a single deck should cost at most $10! Also, like all my formats, it's explicitly proxy-friendly.
Officially, there's no banlist, meaning silver-bordered cards, Braids, and Upheaval are currently legal, but you should discuss that with your play group to make sure everyone's having fun.
