Part 5 of my Weird Things You Can Do in Magic: The Gathering series goes Commander, with a combo whose goal is not to win but to reach a perfectly absurd end state.
The goal
By the end of this line I control no permanents, hold no cards, have an empty library, and nothing in exile. All 100 cards of my Commander deck sit in the command zone at once. That is the whole point: total, useless perfection.
How it works
With Vadrok, Apex of Thunder as my commander, I make infinite mana and draw my deck, then chain a long sequence of pieces including Claws of Gix, Dream Trawler, Epitaph Golem, Mastery of the Unseen, Emergence Zone, Saheeli's Artistry, Leadership Vacuum, and Narset's Reversal. Manifesting the library and repeatedly mutating Vadrok lets me bounce cards to the command zone over and over. It costs a little over 9,000 mana, most of it commander tax that Magic Online refuses to auto-pay, so there is an extraordinary amount of clicking involved.
Credit for the idea goes to Reddit user skycopter and the badMTG combo subreddit. If you feel sorry for all that clicking, maybe share it with a friend.
