For context, Fermats last theorem is highly regarded as one of the greatest mathematical accomplishments in history, with it taking over 350 years to complete, and with entire branches of mathematics seeing advancement just from efforts to make progress on it, if any card deserves mythic I really believe this fits the criteria. At the very least- it deserves a lot more than just an abilityless common. Maybe make it an ultra fusion or something with some actual abilities that explore the properties of the theorem?
I havent thought too specifically yet but I think everyone (who's in the know about their math history) agrees
