I agree with your assessments for every other format, both based on what I know about them and deferring to y’all’s obvious expertise as I stick to commander and sealed events.
However! There are absolutely commander decks that it would make sense in - a fliers-matter Elminster is the obvious choice. It’s fodder for his (-) ability most times but can be cast in the late game if needed for protection and/or just a big body. Not hard to see it swinging in for 20+ flying in that kind of build which is usually lethal in the late game. It’s also one of those cards that is going to send a certain kind of player on tilt against it, which can absolutely be used to your advantage. That sort of thing is going to depend on the meta wherever you play.
