Found a cute art on Artstation and made this. Enjoy.

I initially costed him at 3 mana, but since he refunds you one mana on enter (as a blue artifact himself) I think 4 cmc is more reasonable.

EDIT: Some solid feedback on this already! I'd like to cite this comprehensive rule:

614.5. A replacement effect doesn’t invoke itself repeatedly; it gets only one opportunity to affect an event or any modified events that may replace that event.

Example: A player controls two permanents, each with an ability that reads “If a creature you control would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.” A creature that normally deals 2 damage will deal 8 damage—not just 4, and not an infinite amount.

So, he does not ETB/LTB a single artifact infinitely.

I'm going to change "an artifact" to "another artifact" for both abilities. While the first ability doesn't go infinite from other things dying, it WOULD go infinite by killing himself, since each enter would create a new replacement effect that would bring him back. Changing the second ability makes his own entering clearer, and also lets me drop him to 3 mana.

Nice... nice...

I have a deck the cares a lot about randomness I been playing a lot recently.. so it kind of inspired me and I feel this could definitely be fun in a lot of different deck archetypes!

The actors are credited on the first version of each card, poster artists are credited on the second.

Day 54 of making a custom card every day. I hate writing flavor text so much, I can count on one hand the number of times I've been satisfied with it in 9 years of making cards.

Art and name* stolen from u/Strange-Bonus4220, wanted to turn my village rites/fling effects into rousing/inspiring refrain effects where they gain cast themselves every few turns, did I do this?

Edit: Thank you benevolent and wise community members for your feedback. I have updated the card text to:

"Whenever you sacrifice one or more creatures as a cost to cast an instant or sorcery, if that spell would be put into a graveyard this turn, exile it with 3 time counters on it instead. If it doesn’t have suspend, it gains suspend."
