You do not need ALL the sets, but you would need at least one hero with each unique ability in order to 100% the game. You’d need to go find the google sheets some built to see the “minimum set” and decide if you want to do it. Some things might be pretty hard to track down at this point. I think the reddit page for the game would probably have the spreadsheet pinned.
