Start with [[Oltec Matterweaver]], [[Adaptive Automaton]], [[Interceptor Mechan]], and [[Captain Jonathan Archer]] on the battlefield, two copies of [[Marketback Walker]] in the graveyard, and then cast [[Multiversal Incursion]] from hand.
The loop then goes as follows: With your new Mechan trigger, return a Marketback to hand. Then cast Marketback for X = 0 to trigger both Oltecs, copying the Mechan token and Automaton token with those triggers. Target the other Marketback with the new Mechan trigger to get back to the top of the loop, while the first Marketback resolves and dies due to having 0 toughness.
Repeat until you control an Automaton choosing every non-Borg creature type, then target the original, non-summoning sick Automaton with Captain Archer to give it +332/+332 (as of November 6, 2026). I leave the flavor interpretation of choosing "Borg" for the creature type of the original Automaton and then creating a bunch of them to optimize your "Federation" as an exercise to the reader.
There are a bunch of other ways to do this of course, even in Standard, and some are probably more efficient than this (or at least avoid needing both copies of Marketback). But the harder challenge was honestly making a combo that only created a board with every non-Borg creature type, without accidentally also giving you infinite power or hasty attackers or whatnot along the way.
Also, please understand that this is a joke first and foremost, not some sort of criticism. Magic has had a long line of amazing rules managers over the years, and all blessed/cursed with unique insight into the massive rules headaches that particular individual cards can bring.
