Edit: Just looking for what cards I will be able to keep in the deck before I upgrade

Summary: What general changes should I make to my deck to create a better version of either artifact Sharuum or flicker sharuum? How can I make these changes for 30$ or so?

Hello,This is my first attempt an an EDH deck since I took a break for a while. I tried to make a deck to flicker ETB creatures but don't have many cards to do this, so I ended up adding a lot of artifacts to sacrifice things and artifact creatures. If anyone can help give feedback that would be great. I don't really have any tutors and I only have about 3 flicker spells. I'm hoping to aim for a sharuum flicker deck, but don't know what I should add or take away to get there. All feedback is welcome!

Thank you for your time,millmatter
