Commander for combo decks

I have been playing commander for some time now and pretty much all of my decks have been some variation of "summon creatures, maybe pump them and kick someone's teeth in" with the greatest variation being witherbloom the balancer. Which to be fair is "summon creatures and use big spells to kick someone's teeth in"

I would be really interested in trying some combo decks. I went through some decks in moxfield and archidekt but honestly am a bit lost still. If you have any commanders or decks you would like to suggest, all colours are welcome. Preferably around bracket 3, but a bracket 4 deck also could well be played in my pod. Even if you don't have an suggestion, i wish you have a great day all the same!
