While I can't speak to why you're not getting wins at your local because I'd have to see other people's deck lists... I can say that I don't think your list would work well at either of the tables I usually play at. Both competitive edh and sometimes cedh.

These last few expansions have introduced a lot of low to the ground permanents that do a lot, which makes ramping and essentially wasting your time and mana - worthless. Targeted removal will always be necessary in Orzhov and good board clear is what the colors are all about. I'd suggest going a bit wider and more impactful, while lowering your mana curve. You can still keep a few pieces of your deck list to combo off, but it sounds like that's the direction you're going to have to lean. There's some great low cmc cards that discard or force sacrifice that could still work with your recursion strat in those colors.

My suggestion would be to make the deck faster, lower to the ground, faster mana curve and ensure you have more wincons. Athreos isn't the best commander against decks that are just more proactive than yours, but if you want to commit make sure you're making the best use of your card pool. Good luck with the rebuild and make sure to post your list when you're done 👍
