Commander 2021
Lorehold Legacies
Exile and copy artifacts back out of your own graveyard. Out of the box, before any upgrades. How we rate precons
Buy Lorehold Legacies on TCGplayer →Quick verdict
Lorehold Legacies is an artifact deck whose commander turns your graveyard into a second hand. Osgir, the Reconstructor exiles an artifact card from your graveyard and makes two token copies of it, so a dead Myr Battlesphere comes back as two. The deck has the big artifacts to make that worthwhile, but it lacks ways to put them in the graveyard on purpose, it runs three board wipes that hit its own creatures, and its mana base has more slow lands than it needs.
TurnZero HQ rates Lorehold Legacies a 3 out of 5 on difficulty and a 3 out of 5 on power, as it comes in the box. That is our editorial read, not an official Wizards rating. The full hundred cards are on the Lorehold Legacies decklist page, and every other precon we cover is on the precon directory.
How the precon plays
Osgir, the Reconstructor is a four-mana 4/4 with vigilance and two abilities. For {1} and sacrificing an artifact, a creature you control gets +2/+0. For {X}, tapping Osgir, and exiling an artifact card with mana value X from your graveyard, you create two tokens that are copies of the exiled card, at sorcery speed. Copying a seven-mana Myr Battlesphere costs seven, but you get two of them, each with its own enter trigger.
Much of the deck is built to fill that graveyard. Faithless Looting , Quicksmith Genius , Key to the City and Daretti, Scrap Savant let you discard big artifacts, and Osgir's own sacrifice ability can turn a used rock into a graveyard card. Scrap Trawler and Sanctum Gargoyle return artifacts to your hand when you want them back instead.
The payoffs are big artifact creatures. Bronze Guardian gets bigger with every artifact and gives the others ward, Alibou, Ancient Witness deals damage whenever your artifact creatures attack, and Wake the Past returns every artifact in your graveyard at once with haste.
What works out of the box
Osgir, the Reconstructor ↗
Turns any artifact in your graveyard into two token copies for its mana value. Every enter trigger in the deck happens twice.
Myr Battlesphere ↗
Comes with four 1/1 Myr. Copied by Osgir, it makes two Battlespheres and eight Myr.
Battlemage's Bracers ↗
On Osgir, it lets you pay {1} to copy the token-making ability, so one activation gives you four copies instead of two.
Alibou, Ancient Witness ↗
Gives your other artifact creatures haste, and deals damage equal to your tapped artifacts whenever they attack. Fresh copies attack right away.
Wake the Past ↗
Returns every artifact card in your graveyard to the battlefield with haste. After a board wipe, it rebuilds the whole board in one spell.
Scrap Trawler ↗
Each time one of your artifacts hits the graveyard, it returns a cheaper one to your hand, which chains well with Osgir's sacrifice ability.
What needs improvement
The deck can't reliably get its big artifacts into the graveyard before turn six or seven. Faithless Looting and Key to the City help, but most of the time Osgir is waiting for something to die. Meanwhile Secret Rendezvous gives an opponent three cards for your three, which doesn't help the plan at all.
Chain Reaction , Rout and Cleansing Nova all destroy your own board too. One flexible wipe is useful in a deck that can rebuild from the graveyard, but three is more than an artifact creature deck wants. See how many board wipes a Commander deck needs for a target.
Upgrade ideas
Each upgrade below starts from something the deck does poorly and says what a replacement card has to do. The cards named are examples, not the only answer: if you own something else that does the same job, or a newer printing does it better, it goes in the same slot. Make one change at a time and play a few games between them, so you can tell which change helped. The general method is in how to upgrade a Commander precon →
1. Put big artifacts in the graveyard on purpose
Osgir needs artifact cards in your graveyard. Discard effects put Triplicate Titan or Myr Battlesphere there without casting it first. You still pay its full mana value for X, but that buys two copies instead of one.
What to look for Cheap spells that discard as a cost and replace the cards. Ones that also make Treasures give Osgir sacrifice fodder.
Cut, for example
Secret Rendezvous You draw three, and so does an opponent. It doesn't discard anything and helps the table as much as you.
Hellkite Igniter A seven-mana Dragon that isn't an artifact, so Osgir can't copy it. Its pump is strong but the deck has better top-end threats.
Add, for example
Cathartic Reunion ↗
Two mana: discard two cards, draw three. Put two big artifacts in the graveyard on turn two.
Big Score ↗
Instant: discard a card, draw two, and create two Treasures. The Treasures are artifacts Osgir can sacrifice.
Unexpected Windfall ↗
The same effect as Big Score with a different mana cost. Running both gives you more discard outlets that also ramp.
2. Add cheap artifacts that replace themselves
Osgir's sacrifice ability and its copy ability both want a steady supply of cheap artifacts. One- and zero-mana artifacts that draw when they go to the graveyard are fodder that pays you back, and Osgir can copy them for almost nothing.
What to look for Artifacts costing one or two mana that draw a card or find a land when sacrificed.
Cut, for example
Dispeller's Capsule Narrow artifact and enchantment removal that costs four mana in total. Return to Dust and Rip Apart already cover that job.
Unstable Obelisk A three-mana rock that only makes colorless, with a seven-mana destroy effect. Cheaper rocks and removal do both jobs better.
Add, for example
Mishra's Bauble ↗
Costs nothing. Sacrifice it to look at a library's top card and draw next upkeep. Osgir copies it for X equal to zero.
Chromatic Star ↗
One mana. Sacrifice it for one mana of any color, and it draws a card when it goes to the graveyard, including from Osgir's sacrifice ability.
Wayfarer's Bauble ↗
One mana, then two more and a sacrifice to put a basic land onto the battlefield. Ramp that becomes graveyard fuel.
3. Trade symmetrical wipes for spot removal
This deck's board is made of artifact creatures it worked hard to copy. Cheap removal lets you answer one threat without destroying your own side.
What to look for One- to three-mana instants that exile or remove a single creature or permanent.
Cut, for example
Chain Reaction Deals damage to each creature equal to the number of creatures. In a deck that makes two tokens at a time, it hits your own board hardest.
Rout Destroys all creatures. Cleansing Nova does the same for the same cost and can hit artifacts and enchantments instead.
Add, for example
Swords to Plowshares ↗
One-mana instant that exiles a creature. Its controller gains life equal to its power.
Path to Exile ↗
One-mana instant that exiles a creature. Its controller may fetch a basic land.
Chaos Warp ↗
Three mana to shuffle any permanent into its owner's library, including an enchantment or a planeswalker.
4. Fix the mana base
Several lands here enter tapped or make only colorless. A deck that wants Osgir on turn four and mana for X the turn after needs both colors on time.
What to look for Lands that tap for red or white and usually enter untapped. The land and mana base guide lists options.
Cut, for example
Temple of the False God Makes no mana until your fifth land, so it is dead in the turns that matter most.
Secluded Steppe Enters tapped and makes only white. Cycling is a small upside next to an untapped dual.
Forgotten Cave Enters tapped and makes only red, with the same tradeoff as Secluded Steppe.
Add, for example
Win conditions
The upgraded deck wins by copying its biggest artifacts and attacking. Discard a Myr Battlesphere or Triplicate Titan , copy it with Osgir, the Reconstructor once you have the mana, and use Alibou, Ancient Witness to give the copies haste and deal extra damage when they attack. Hellkite Tyrant is an alternate route if you can keep twenty artifacts, and Wake the Past rebuilds the board after a wipe.
Who should buy this precon
A good fit for a player who likes graveyard decks and enjoys planning a turn or two ahead. You have to decide which artifact to discard and when to spend a whole turn's mana on Osgir's copy ability, and track which cards are worth copying. It is moderate in difficulty and not ideal for someone who wants a straightforward attack deck.
