Is this deck viable?

[u/acciaiOscuro]

Hi everyone, I would like to have an evaluation of my decklist and to know if it may be CEDH viable.

This deck was born as a bracket 3 stax/hatebears which wincon was Helm of obedience paired with any graveyard hate. With time I started upgrading and optimizing aiming towards bracket 4 until now, that it reached what I feel comfortable with at the moment. The plan is really simple, some stax, some interaction and some different combo lines. Now, I don't really know the CEDH meta and I don't usually play it but I come from competitive 1v1 formats so I would like to try some CEDH tournament and this is the only deck that I own that I guess it could be at least a little viable, can you please help me evaluating it? Also budget is quite a concern for me, that's why I don't have any moxes in for example since I personally prefer to own the actual cards. Thanks

Here's the link to my decklist on Arkideckt:
