Alright, so. This is a Glissa, the Traitor deck. I had wanted to make one for a while but never really had a good idea for it, but then one day I realized it was the perfect place for a weird infinite combo and it all sort of came together into a really fun artifact-based aristocrats type build with several paths to victory.
So, first thing's first. Artifacts. The deck is made to sacrifice and recur artifacts, not just with Glissa's effect, but also things like Junk Diver and Myr Retriever. A lot of the slots that would be for utility instants or sorceries are replaced by artifacts with either a useful ETB or a way to sacrifice themselves for an a benny. Most of those draw a card for you, too, so between cantrip artifacts and recursion, plus Skullclamp and Carnage Altar, you've got card advantage for days.
Speaking of Glissa's effect, we've got Dictate of Erebos, a few spot removal cards and some board wipes to keep creatures dying to keep triggering her ability. Genesis Chamber pulls double duty of giving you more artifact creatures of your own to sacrifice, and giving your opponents more fodder creatures to die.
The non-artifact cards in the deck are just all around useful effects. Entomb and Buried Alive are great tutors for our artifacts to be recurred by Glissa.
Disciple of the Vault, Zulaport Cutthroat, Syr Konrad and Marionette Master are our aristocrat pieces, gotta keep draining life for all of our artifacts and artifact creatures dying. You should be able to keep those dies triggers coming in general, but there's something else!
The big combo of the deck is Titania's Song and Pitiless Plunderer, those two are a chain of infinite ETB/dies triggers of artifact creatures tokens, and any one of our aristocrats gives us a payoff to win the game.
You can also go infinite with Deathrender and some combination of Myr Retriever, Junk Diver, Workshop Assistant and Scrap Trawler.
If that's not your style, there's Revel in Riches. You're killing a lot of creatures already plus you've got some other ways to make treasure, even at instant speed, so it's easy to trigger that win condition.
If you're looking for a more brute force approach, Traxos can be equipped with Blackblade Reforged and go in for some big damage. And Arcbound Ravager is there to either get big on it's own, or dump those counters onto Traxos.
If that still doesn't give you the fizz, just fill your board with treasures and clues, then slap a Cranial Plating on Glissa and Rogue's Passage your way to victory with commander damage.
Of course, Traxos can use Cranial Plating or Glissa can use Blackblade Reforged just as easily.
A few of the cards are a bit more narrow, but useful if you need them. Codex Shredder can get back any of our non-artifact cards then itself get recurred and Nihil Spellbomb is there just cause sometimes graveyard decks can get out of hand.
The mana base doesn't need to be too fancy, most of the deck is colorless, and with mana rocks and artifacts that give you land ramp, you're golden. Besides the three artifact lands and Rogue's Passage, the rest don't really matter.
(The reason the deck doesn't have an Overgrown Tomb is that I just ran out of them.)
