This deck was born from a strange desire I had to make a mid-power Grixis artifacts deck. In general, Grixis is outclassed by Izzet and Esper colors for artifact shenanigans (also by mono-U with Urza, Lord High Artificer and Breya, Etherium Shaper's four colors). However, for this deck, I wanted to make it more fun and slightly jank rather than competitive. That meant I didn't want to mess with Mishra, Artificer Prodigy since I thought playing Mishra stax, while kind of cool, would not be super fun for the pilot or anyone else. I also avoided infinite mana stuff like Grim Monolith + Power Artifact or Isochron Scepter + Dramatic Reversal since that's all been done to death, and not really worth going into Grixis colors for.

This deck is focused on getting infinite turns with Time Sieve. To accomplish this we need tutors, artifact recursion, and a way to consistently feed it. To this end, Kraum, Ludevic's Opus and Silas Renn, Seeker Adept make for an ideal commander pair to lead this deck. Kraum gets you card advantage and is a flying threat once you've got infinite turns rolling, and Silas gets you some half decent artifact recursion as well as the color black, which has some nice tools for the strategies we're going to use.

Tutors

Goblin Engineer, Gamble, Muddle the Mixture, Shred Memory, Fabricate, Whir of Invention, Tezzeret the Seeker, and Inventors' Fair. There are also plenty of venues for card advantage, which will hopefully either get you to Time Sieve or to one of these tutors quick enough to win.

Whir of Invention is the most powerful of these, being able to put your Sieve directly onto the board, potentially pretty early with enough artifacts. However, you should never play your Time Sieve unless you are able to activate it the turn you put it down. Whir is also versatile, because if you already have your Sieve, you can tutor up a Thopter Assembly or Myr Battlesphere for potentially much less than it's true cost.

Feeding The Sieve

Thopter Assembly is probably the most well known way to feed the Time Sieve. However, you have to wait until your upkeep for it's ability to trigger, which is a very long time for someone to kill it, bounce it, or do whatever they want with it if they have an inkling of what you're up to. Flashing it in with Shimmer Myr right before your turn is a good idea if you can do that.

Of course, if you have enough Servo/Thopter producers, it's possible you might be able to keep Sieve going long enough to find a more efficient solution. Such producers would include: Sai, Master Thopterist, Saheeli, Sublime Artificer, Efficient Construction, Thopter Spy Network, and Tezzeret, Artifice Master.

If you have Myr Battlesphere, a Goblin Welder, and one of the aforementioned Servo/Thopter producers, you can still go infinite with Time Sieve. Play the Battlesphere, and sac it to the Sieve along with the four Myr tokens it brought with it. Then on your next turn, use the Goblin welder to sac a Servo/Thopter or whatever you want to get the Battlesphere back and repeat.

All the Time in the World

So what do you do with infinite turns? It seems to follow that if you achieve this, you should win the game. This is a little counter-intuitive when you think about it a little bit, if you don't know what your actual wincons are.

Disciple of the Vault and Marionette Master will hurt people whenever you sac artifacts for the Time Sieve loop. Geth, Lord of the Vault can kill people or mill them out (or both). Tezzeret the Seeker's ult can sometimes do good for you, and Tezzeret, Master of the Bridge's +2 can do a lot for you as well. You also have strong flyers in the form of Kraum, Ludevic's Opus, Hellkite Tyrant, and Steel Hellkite. Cranial Plating can help you get the job done faster in this regard. Hellkite Tyrant can also straight up win you the game with the amount of artifacts you have (or will eventually have). A combination of some or all of these will kill people the fastest (obviously).

Winning the game after you get the infinite turn lock is definitely the jankiest part of this deck!

That's it! I might make more updates to explain stuff better in the future. In the meantime, upvote if you like the deck, and comment with any suggestions you have. Thanks!
