This was a great read, I'm just starting to get back into MTG with strixhaven! I have a couple thoughts. Would you mind sharing some of the more janky combos you mentioned in the infinite combo category? Also, could you explain how exactly I would go about getting more than 2 copies of an artifact?

Side note: I confirmed in the ask a judge chat that bronze guardian's ward2 is additive with each additional copy of bronze guardian on the field.

Hey kuromadei, thanks for the comment and upvote, much appreciated.

Thanks for pointing out that Bronze Guardian 's ward ability does in fact stack. I actually just recently watched an episode of the command zone podcast where they point this out, and was going to update the primer today. Makes the card quite a bit better than I originally thought it'd be in the deck.

For your question about more than two copies: Anointed Procession will trigger anytime we create a token, which includes Osgir, the Reconstructor 's second ability. Illusionist's Bracers will trigger much in the same way when it's equipped to Osgir, and Rings of Brighthearth will allow us to pay to copy Osgir's second ability. Basically all these interactions will allow us to copy / double Osgir's second ability creating four token copies of whatever we're targeting. We can then increase the amount of tokens created by having multiples of Illusionist's Bracers / Rings of Brighthearth or adding Mirage Mirror .

For your question about the jank combos: I actually just discovered a new combo line while taking a second look at the janky ones, so HUGE thanks to you for helping me discover this line!! I'll be adding it to the primer shortly...

Eldrazi Displacer + Krark-Clan Ironworks + Myr Battlesphere + Goblin Engineer . Sacrifice all four myr tokens to Krark-Clan Ironworks generating 8 mana. Then use that mana to activate Eldrazi Displacer blinking Myr Battlesphere / Goblin Engineer . This will tutor an artifact to the graveyard and generate another four myr tokens. We can then repeat this an infinite amount of times generating infinite mana and tutoring every artifact to our graveyard.

Here's where the JANK comes in...

Once all of our artifacts are in the graveyard, and we have infinite mana, we can then use Umbral Mantle to continuously untap Osgir, the Reconstructor activating his second ability an infinite amount of times to reconstruct every artifact in the graveyard. We can then add Quicksmith Genius to the line to draw / discard the entire deck or Reckless Fireweaver to deal an infinite amount of damage to all our opponents.

Another janky line to tutor every artifact to the battlefield, draw / discard the whole deck, or deal infinite damage to our opponents:

Krark-Clan Ironworks + Myr Battlesphere + Anointed Procession + Goblin Welder + Kuldotha Forgemaster + 2x Umbral Mantle . (This will require Kuldotha Forgemaster / Goblin Welder to both be equipped with a copy of Umbral Mantle . Myr Battlesphere entering the battlefield will trigger Anointed Procession creating 8 myr tokens. Sac three of them to Krark-Clan Ironworks to generate 6 mana. Then sac 2 more and Myr Battlesphere to Kuldotha Forgemaster to tutor an artifact to the battlefield. Use the 6 mana we still have floating to activate the umbral mantles equipped to Kuldotha Forgemaster / Goblin Welder untapping them both. Then sac one more myr token to Goblin Welder to get the Myr Battlesphere back out of the graveyard. When Myr Battlesphere re-enters the battlefield this will re-start the loop. Repeat as many times as necessary to tutor every artifact to the graveyard. There a few different ways to start this loop which just include different ways of getting the ETB trigger from Myr Battlesphere , but you'll have to forgive me for not diving deeeper into that. Again we can also add Quicksmith Genius to the line to draw / discard the entire deck or Reckless Fireweaver to deal an infinite amount of damage to all our opponents.

The above combo will also work if we swap Wurmcoil Engine or Triplicate Titan for Myr Battlesphere .

Thanks again for encouraging me to take a second look at the combo lines, and the comment / upvote! Hope this helps! Cheers!

Hey kasprl, thanks for the comment and upvote, much appreciated.

Happy to hear you like the list, and it gave you some ideas. Would be curious to see what you come up with for your own build. Let me know if you ever need any help with it, or want me to take a look. Cheers.

Hey there unstable_anomaly! Thanks for upvoting my decklist for my own Osgir, thought I'd jump in the thread and return the favor ;)

So I noticed something in your deck explanation, specifically the doubling with Anointed Procession in play. In the comprehensive rules, if you've got 2 Processions in play, you double each instance. So say you make 2 Sol Rings off Osgir, with 1 Procession in play you make 4, but with 2 in play you make 8, 16, 32 and so on for however many Processions you've got. Since we play Mirage Mirror (I mean, come on its such a good card) we can effectively have 4+ Processions active at any given point. If you knew this, please put me in my place, otherwise I hope I enlightened you! ^-^

Aside from that I am impressed with what you've created with your own Osgir deck, he's very powerful and effective at utilizing cheap mana rocks and card draw for a great value engine!

Hey MaltOMeal, thanks for the stopping by, really appreciate the comment and upvote :)

To tell you the truth, I hadn't actually thought about making multiple copies of Mirage Mirror or had the chance to do so in any of my playtesting. You have indeed enlightened me! Mirage Mirror truly is an amazing card that I'm starting to run in more and more of my decks even if it doesn't necessarily fit the theme, but when paired with Osgir it's almost too good.

Osgir is easily my favorite commander at the moment, I've been having a blast playing him. So many shenanigans!

Does Walking Ballista have some synergy I'm not seeing here? It is a great mana sink but Osgir can't bring it back if it dies correct?

@magicmuth No he is mainly just a mana sink in decks like this as he comes into the battlefield from the GY w/ x==0 so a 0/0 creatures that dies instantly. You would still get any "etb/ltb" triggers from its copies from Osgir but that's about it.
