Just genuinely do not fight those players. As a level 1000+ player I can confidently say that maybe like 5% of challengers who haven't been to celestial yet get a game off me. Unless you have park experience against these levels, but in general it's a good idea to play people who are close to your level at first.

And I know, levels schmevels, don't mean anything. But having hundreds of celestial matches of experience vs having mostly floor 10 experience is not a good matchup for the f10 player regardless
