Gonna preface this with the fact that I know nearly nothing of the pauper meta but are, 3,4,5,6 drop creatures with nothing cheaper than that a normal thing in Pauper? Seems like a bad time in most all other formats. Some cool cards I've never known existed here though, lol.

The most accessible format! In Pauper, all cards in your deck must have been released at common rarity in a Magic set or product.

Idk anything about the pauper meta either, but looking closely at the cards and their interactions tells me it's a control deck.
The cheap spells at 1 and 2 CMC are removal and discard to take care of early threats. Some of these spells produce an artifact, which feeds the other spells with low CMC but additional cost of sacrificing an artifact. Lots of card draw too, which is key for control.
Eventually, the player should reach a point where they have a stream of disposable artifacts to control the board, and extra mana to drop fatties or dump into crypt rats for life loss.
This is creative and looks like a lot of fun to play!
I wish I could take the credit. Its a fairly standard (if newish) Meta deck for Pauper. about 6% per

Its sometimes called Golari Gardens instead.
It is very fun to play, it can be a little frustrating against another control deck though. Or burn decks. Its awesome against aggro decks that rely on creatures. It also tends to be a little slow to get going unless you get a REALLY good draw.
