You do have to like the commander and what it does (and the singleton and multiplayer format), but it sounds like you don’t have the time to find out what that is, since yours get removed often and quickly. Getting obliterated is never fun, even when you love the format and the commander
If they have only high power decks, yeah you’re better off trying to find a new-ish commander and proxy a whole deck around that. Keep in mind that usually older precons are pretty underpowered compared to newer cards. Still, since you sound new to EDH they could at least make an effort once and either borrow a precon or build something low power with the spare cards they have, if possible.
maybe mtggoldfish on yt with their brewer’s kitchen and against the odds playlists
