How to keep track of cards across multiple Commander decks

The moment you build a second Commander deck, a new problem appears: is that Sol Ring in the Atraxa pile or the Rhystic Study pile? Do you own a second Cyclonic Rift, or did you swap it between decks three weeks ago and forget? Five decks in, this becomes genuinely exhausting to manage in your head.

Why tracking gets hard fast in Commander

Commander is the most card-hungry format in Magic. A single EDH player can have 400 to 1,000 cards spread across several independent 99-card decks, all competing for the same staples: Sol Ring, Arcane Signet, Cyclonic Rift, Rhystic Study, and commander-specific pieces. Unlike a Standard or Modern collection where most cards have clear homes, a Commander collection is in constant flux — cards rotate in and out of decks as you tune, upgrade, and rebuild.

Most players hit one of two failure modes: they buy duplicates of cards they already own (because they couldn't remember which deck had the original), or they accidentally cannibalize a working deck to fill holes in a new one and then can't reassemble the first deck later.

The "one physical location per card" method

The simplest and most reliable physical rule is this: a card lives in exactly one place — either in a deck box, in a general binder, or in a trade/sale stack. It is never in two places at once. This sounds obvious, but it breaks down when you pull a card out "just to test it" in another deck and never put it back.

Enforce this with a physical inbox. A small box or sleeve stack where displaced cards land at the end of each game night. Before you put decks away, you reconcile: every card in the inbox either goes back to its deck or gets reassigned. This discipline alone eliminates most of the "where is my Smothering Tithe?" moments.

Should you buy staple duplicates?

For true format staples — Sol Ring, Arcane Signet, Command Tower — yes. These are cheap enough that owning three or four copies and putting one in every deck is more convenient than shuffling a single copy around. For expensive staples like Cyclonic Rift or Rhystic Study, it depends on how often you actually play each deck. If two decks really want the same card and you play both regularly, the duplicates pay for themselves in reduced frustration.

The problem is knowing which staples you're missing in which decks before you're sitting at the table about to shuffle up. That's a tracking problem, and physical organization alone doesn't solve it.

What a digital inventory actually solves

A digital collection tied to your decks gives you three things physical organization can't:

• Search across all decks at once. "Do I own a Smothering Tithe?" resolves in one tap — and tells you it's in your Kaalia deck.
• Flag cards in multiple decks. If you're building a new deck and want to pull a card from an existing one, you can see exactly which deck would lose it and decide whether you want to buy a second copy or cannibalize.
• Know your total collection value. When cards spread across ten deck boxes, it's easy to forget you have hundreds of dollars of staples you'd never sell because you never see them all together. A digital total makes that visible — useful when getting proper insurance coverage.

Setting up Archivist for a multi-deck Commander collection

Archivist is built around the idea that your physical and digital collection should match. Each deck lives as its own deck in the app, and each physical box or binder you own is a location. Scanning cards into a location while also assigning them to a deck keeps both layers in sync.

For a multi-deck Commander setup, a practical approach:

1. Create a location (box) for each Commander deck. This is where each card physically lives.
2. Create a deck for each Commander. The deck list lives here — 99 cards plus your commander.
3. Scan each deck once using the iPhone or Mac camera. On-device OCR reads the card name, set, and collector number in under a second per card. The first scan is the investment; staying current after is just scanning new cards as they go in.
4. Keep a "binder" location for general staples and trade stock that aren't assigned to a specific deck yet.

Once scanned, you can search your whole collection across every location and deck. Before buying a card for a new build, a quick search tells you if you already own it — and where it is.

Price tracking across a distributed collection

One underrated benefit of having all your Commander decks in a single digital collection: you see the total value and can set price alerts on individual cards regardless of which deck they live in. When a card spikes in price, you get notified whether it's in deck number two or deck number eight. This matters if you ever want to upgrade a deck — sell a card that spiked and buy a more synergistic replacement for that slot.

The practical minimum

You don't have to digitize every card on day one. Start with just your most-played deck and one binder of loose staples. Even a partial index is more useful than no index — the first time a search saves you from buying a duplicate, it pays for the time you spent scanning.
