after spending $300, i think it's still bad lol

Here's the decklist

Basically got into commander maybe 2-3 months ago, but have been playing Standard for probably 1-2 consecutive years. But I've been spending money to work and build this deck and have only found that it still loses speed or can never start. Whenever I play EDH games at my local card shop, I get swept well before I can even make moves. Obviously not looking to buy more cards, but I'm wondering if anyone's had this experience, and what you guys do to avoid it. (My assumption is playing Mox/Archidekt beforehand, WHICH I HAVE STARTED DOING)

OKAY GUYS I SEE IT ALL CLEARLY NOW, I HAVE BEEN ENLIGHTENED
My deck has no clear direction, cmc is WAY too high, barely have ramp, and the deck is mostly goodstuff without much synergy. Also, I was kinda building this with a 1v1 mindset, which obviously doesn’t work in 4-player Commander. I'll be cutting down on the big dumb creatures that just clog my hand, adding more ramp and better lands (fetches, signets), and actually committing to a real game plan instead of just “Muldrotha good.” And maybe at some point the goodstuff will find a home in a much more focused deck lmao. Will update the deck for once I feel like it's good, I appreciate all the help :D
