A commander player for 10+ years and a Magic player for 28, I came to cube design through the pandemic after having played only a small handful of cubes. A Johnny at heart with a Spike's appreciation of optimization, the hurdles of designing a custom metagame appealed to me as a challenge as someone who has built hundreds of decks over the decades - here was my opportunity to create hundreds of decks in a single package.
Since getting into cube, I've added pioneer to the list of formats that I focus on as an appealing midpoint between the rotation of standard and the high barrier of entry of modern.
