Saheeli the Oathbreaker
"The Mother of Invention"
A few of the newer members of our playgroup brought up the idea of trying out Oathbreaker. Thought it sounded like a good time. However after a bit of conversation on what people wanted to build we decided that it would probably be in ever ones best interest if we limited the crazy shenanigans a bit by putting a $100 budget on deck building. After a bit of consideration and playing around with a couple of ideas I ended up building a pure value deck cough eggs cough with Saheeli, Sublime Artificer and Thoughtcast.
Artificers:
These are the cards that reward us for playing as many artifacts as possible.
Reckless Fireweaver: Can very possibly end the game by himself as he hits all opponents at once when an artifact enters play.
Sai, Master Thopterist: A more specific version of commander that lets us double up on the token generation letting us go wide if all else fails. Not to mention the built in ability to draw us more cards!
Pia and Kiran Nalaar: While they do not reward us immediately for playing artifacts they do grant us blockers along with the ability to remove threats from the field.
Etherium Sculptor: Allows us to play more artifacts so that we can draw more cards to play more artifacts to draw more cards to play more artifacts to draw more cards to play more artifacts to draw more cards to play...
Master of Etherium: This guy lets us go for more of a beat down strategy. So if all else fails we just kill out opponents the good old fashioned way.
Junkers and Traders:
Cards that allow us to get artifacts into and out of our graveyard whenever we want.
Buried Ruin: A land that allows us to trade it for the artifact of our choosing.
Trading Post: The Swiss army knife of artifacts. It slices! It Dices! It brings all the goats to the yard!
Krark-Clan Ironworks: Pretty self explanatory allows us to trade artifacts for mana.
Ashnod's Altar: While not quite as good as KCI Altar still allows us to generate mana from our Servos and Thopters.
Myr Retriever: Allows us to trade this guy for a artifact of our choice from our yard.
Scrap Trawler: Myr Retreiever of steroids.
Daretti, Scrap Savant: One of the best cards in this deck. Thankfully he has been reprinted into oblivion allowing us to play him with very little harm to our budget.
Win Conditions
How we close out the game.
Reckless Fireweaver/Psychosis Crawler These both allow us to kill everything and everyone for using our commander and signature spell.
Krark-Clan Ironworks + Scrap Trawler + one of our three zero drop artifacts (Mox Amber, Ornithopter or Everflowing Chalice). While not infinite this setup allows us to generate an insane amount of mana, card draw, and tokens.
Been enjoying the little bit of Oathbreaker that we have been playing while similar to commander its different enough to be refreshing. Hope you find this list helpful. And as always happy draws!
