I recount here on paper, online only, and combined on paper/online deckbuilding challenges

This is a combined on paper/online challenge. The objective is to understand if it is possible to have a set, which I call Commanders Masters, that can be played sealed or in draft for a Brawl or Commander build. I am going all the way on this one and aiming for a Commander build, which requires a gigantic number of cards. I love giant sets like Tenth Edition. That's my bias. And if a Commanders Masters set seems not feasible, then I can turn the result of this challenge into a commander cube. I hope you join me on this fun ride. I have already pulled a first selection, and have a playlist on YouTube for that work(link in the challenge page linked above).
