Yeah, for me the issue is that they are just second copies of Tireless Tracker but worse. Same cost, similar role and slots in the same spot. If you have to choose, the right answer is Tireless Provisioner but I would take anything else.
Interestingly, the card that has boosted green-based artifact decks the most for me is:
It being a land really makes you interested in green. There's also a tendence for Workshop decks to be Bazaar of Baghdad decks so that's two for one. AND, these are often Welder decks, which like Green's tutoring. If you really want to push this angle, I found this card to help.
Since it allows you to replay your Welders and Smokestacks, giving you the valuable redundancy the deck usually lacks. However, it's redundant with other green crucible effects so I cut it. Also, slow or not, it does give you infinite recursion which can feel pretty bad depending on the card.
You already run a card that ties green to artifacts, though and it's
Samwise Gamgee. That thing produces a lot of tokens and valuable recursion.
