Osgir (EDH / Commander)

Overview
This is a very commander-centric deck, as it relies on [[Osgir, the Reconstructor]] to do most of the cool stuff. The primary game plan involves playing [[Osgir, the Reconstructor]] and activating it as much as possible. Because [[Osgir, the Reconstructor]]'s token-producing ability can only be activated as a sorcery, this deck tends to play almost everything at sorcery speed.

Artifact Land Ramp
[[Osgir, the Reconstructor]] can exile an artifact with mana value 0 from the graveyard. This includes artifact lands and other mana-producing things. Playing an artifact land, tapping it to activate [[Osgir, the Reconstructor]]'s sacrifice ability, then tapping [[Osgir, the Reconstructor]] to reanimate the land basically turns a land play into 2 lands plays. The artifact lands include:

• [[Ancient Den]],
• [[Great Furnace]],
• [[Darksteel Citadel]],
• [[Rustvale Bridge]],
• [[Treasure Vault]], and
• [[Power Depot]].

This is my favorite interaction in the entire deck and made the difference between me making the deck and not making the deck.

Activating [[Osgir, the Reconstructor]] Even More
There are many ways to get extra activations out of [[Osgir, the Reconstructor]]. First, there are untap cards, which include [[Patriar's Seal]], [[Thousand-Year Elixir]], and [[Magewright's Stone]]. Then there is [[Mondrak, Glory Dominus]], which double's [[Osgir, the Reconstructor]]'s reanimation ability. Making 4 tokens with one activation is pretty sweet. Finally, there is [[Illusionist's Bracers]], which will also double [[Osgir, the Reconstructor]]'s token-producing ability.

Drawing Cards
There are a bunch of cheap artifacts that draw cards. These can be played, sacrificed, and then brought back with [[Osgir, the Reconstructor]] for more card draw. Most of them turn into 0-mana or 2-mana "draw-threes." [[Ichor Wellspring]] can draw 6 cards for 4 mana, which is pretty neat.

Winning the Game
There's a few major cards that can go very big. These include:

• [[Scrap Mastery]],
• [[Wake the Past]],
• [[Brilliant Restoration]], and
• [[Saheeli's Directive]].

Most of these put a ton of artifacts onto the battlefield, which can result in overwhelming value. It's important to be aware that these cards are something to work towards, and it is often a good idea to play with that in mind.

Besides these cards, there's also big creatures that can act as win conditions.

• [[Triplicate Titan]] can be played, sacrificed, brought back with [[Osgir, the Reconstructor]], and sacrificed twice more for a total of 9 creatures.
• [[Wurmcoil Engine]] is similar to [[Triplicate Titan]].
• [[Parhelion II]] can be crewed by [[Osgir, the Reconstructor]] and takes over the game if not dealt with.

Another good line to take is to attack, wait for no blocks declared, and then sacrifice a bunch of artifacts to [[Osgir, the Reconstructor]] for a big lethal pump.

If winning is proving difficult, then [[Platinum Angel]] and [[Platinum Emperion]] can help prevent losing for a while. [[Ethersworn Canonist]] and [[Lodestone Golem]] are pretty one-sided and can slow other players down. Getting multiple copies of [[Lodestone Golem]] is also pretty nice.

My favorite single card in the deck is [[Soulscour]]. This can often result in a "free win." [[Scourglass]] does a decent [[Soulscour]] impression.

Finally, there are [[Mindslaver]] loops. [[Goblin Welder]] can repeatedly bring back [[Mindslaver]] and control someone's turn enough times to lock them down. Sometimes a value [[Mindslaver]] with [[Osgir, the Reconstructor]] (that only activates 3 times total) is enough to "turn off a player" long enough to kill them or get a win.

Other Notable Cards

• [[Illusionist's Bracers]] is meant to double [[Osgir, the Reconstructor]]'s token-making ability, but it can also do other things like double activations from [[Goblin Welder]] and [[Goblin Engineer]]. It also incidentally double's [[Osgir, the Reconstructor]]'s pump ability, but that's not too important.
• [[Faithless Looting]] and [[Thrilling Discovery]] can help get cards into the graveyard for [[Osgir, the Reconstructor]] to target.
• [[Coveted Jewel]] can draw three cards, tap for 3 mana, and then get sacrificed to do it all over again.
• [[The One Ring]] is excellent card draw and it can be sacrificed if it gets too many counters on it.
• [[Wheel of Fortune]] draws a lot of cards, but it also fills up the graveyard for [[Osgir, the Reconstructor]].
• [[Daretti, Scrap Savant]] does a triple job of filtering cards, filling up the graveyard, and reanimating artifacts.
• [[Karn, Scion of Urza]] is primarily for card draw, but the tokens can also get very large.
• [[Goblin Engineer]] can get a lot of stuff into the graveyard, but when in doubt just grab [[Sculpting Steel]] because it is the most versatile and it can be swapped by [[Goblin Engineer]] itself.
• [[Liberator, Urza's Battlethopter]] provides good surprise factor. It's a little awkward because [[Osgir, the Reconstructor]]'s primary ability can only be activated as a sorcery.
• [[Krark-Clan Ironworks]] turbo-charges the deck, especially with all the artifacts that draw when they get sacrificed. Often times you can sacrifice something to [[Krark-Clan Ironworks]] just to bring it right back with [[Osgir, the Reconstructor]] for value and/or a burst of mana.
• [[Comet, Stellar Pup]] is a good boy.
• [[Prototype Portal]] acts kind of like a backup [[Osgir, the Reconstructor]]. If you put an artifact land under it, it just makes a land every turn for free! Of course, it also provides plenty of other options as well.
• [[Angel of the Ruins]] is super nice because it can cycle and then get targeted by [[Osgir, the Reconstructor]] to exile 4 things later on (not to mention the two 5/7 flying bodies).

Maybeboard Considerations and Exclusions

• Other token doublers ([[Anointed Procession]]).
• [[Foundry Inspector]] has proven to be a good card, so maybe [[Cloud Key]] belongs in the deck too.

There are a lot of fun cards that just don't fit the theme

• Good interaction like [[Swords to Plowshares]] and [[Tibablt's Trickery]] get worse when the deck operates at sorcery speed so much.
• [[Burnished Hart]] seems ok, but then again, going through the full [[Osgir, the Reconstructor]] loop with it costs 15 mana and gets 6 basic lands. There aren't really enough basic lands in the deck to make that work and it's just too mana-intensive.
• [[Treasure Nabber]] is funny because you can sacrifice other people's mana to [[Osgir, the Reconstructor]]. However, it's not an artifact itself and just killing everyone's random signets doesn't feel as great as playing more proactively.

I cut a lot of good cards out that were too generic, like [[Blasphemous Act]], [[Smothering Tithe]], and [[Cathartic Reunion]]. I wanted the deck to use as many cool/unique/fun cards as possible.

I tried out the suspend mana artifacts ([[Sol Talisman]], [[Mox Tantalite]], and [[Lotus Bloom]]). They were good when they could be discarded and brought back with [[Osgir, the Reconstructor]], but they were not very good when actually suspended. Drawing [[Mox Tantalite]] on turn 3-4 feels really bad if you can't discard it. A card like [[Talisman of Conviction]] would be much better because you can play it for -2, tap for +1, sacrifice for -1, [[Osgir, the Reconstructor]] it back for -2, then tap both for +2; you end up spending 2 mana to cast a tapped double mana rock. That's a lot better than suspending [[Sol Talisman]] and doing nothing for 3 turns. I will have to see about adding more mana artifacts to the deck if it proves necessary.
