[EDH] [Opinion] [Suggestions] [Casual Play] Arty - Golos

Arty is my personal name for the deck because it's nearly all artifacts and Golos is the commander.

Looking for some suggestions to improve this EDH deck I've built and tweaked and tweaked. The goal behind the deck is to be a 5-colour-colourless deck. With Golos as commander I believe I have the land stuff sorted out and have been able to trigger his ability during a few games.

A couple things I'm looking for help on if possible is ramp, card interactions and draw power. I've played the deck a few times in 1v1 and 1v3 and the previously noted issues have occurred. But I have had a few wins with the right opening draw.

The goal of the deck is to be entirely colorless for everything except Golos. My general style of play is to get/build big fat chonkers and just smack opponents with damage. I'm not sure if that works with this deck or not so I'm a bit lost. I think what I need for this deck rather than big fat beasts is card interactions that get to a win condition. I'm not a fan of infinite combos, would rather enjoy the gameplay to the end.

So here's the link to the Deck as it stands today: https://deckbox.org/sets/2730952

And I don't want to spend money, I would like to use my existing inventory which you can see here: https://deckbox.org/sets/2479290

Any thoughts would be awesome!
Thanks in advance!
