Search your collection for the cards your deck needs

You're putting together a Commander deck. The list lives in Moxfield, Archidekt, or a paper notebook on the kitchen table. You've got fifty cards left to find. Some of them are sitting in your binder right now. Some are sitting in your friend's binder. Some you'll have to buy. The first question — and the one most tools skip — is: which of these do I already own?

MTG Burrow's deck-building search utility answers that question. It is not a deck-construction interface. The site does not let you assemble or store decks; the deck construction stays wherever you already do it. What MTG Burrow does is search your MTG collection (and, optionally, your playgroup's) for the cards your decklist references, so the next box you open at game night is for the cards you actually need to acquire — not the ones sitting in your friend's commander deck pile.

Search collection for deck cards across owned and group binders

The flow is straightforward. Sign in, open the deck-build search, and run a query. Queries support the same Scryfall-style syntax used elsewhere on the site (t:dragon mv<=4, o:"draw a card", is:commander color:wu), so a search for the cards your deck needs maps cleanly to the way you already think about Magic. The results are scoped to your collection by default: every card you own that matches the query, with the printing and quantity you have. Switch to the group scope and the same query searches across every collection in your playgroup, telling you which friend has the Cyclonic Rift you can borrow or trade for.

This is what searchers using "MTG deck builder from collection" or "Commander deck builder owned cards" are actually looking for: not another decklist editor (Moxfield and Archidekt already do that well), but a way to find cards from collection MTG resources they already control. If you're using an MTG deck builder like Moxfield, the deck-build search is the missing layer between the list and the binder.

Compare what you own against what your decklist needs

Bring a list, see the gap. The site includes an MTG deck diff flow that takes your decklist (paste it in, or upload a .txt) and compares it against your collection. The output is a clear two-column read: what you already own, and what you still need. Run the same diff against your group's pooled collection and the "still need" column shrinks again — what you still need to acquire from outside the group is what you'll actually buy. Many users tell us this is the single most useful thing the site does, because it converts an abstract decklist into a concrete shopping list.

The deck diff is auth-gated because it operates on your private collection data, but the workflow is the central value proposition of this MTG deck building search tool: deck → diff → trade or buy. No deck construction is happening on MTG Burrow itself. The construction happens on Moxfield or wherever you already build. The site fills in the "what do I own?" step that nobody else has filled in.

Built for Commander, but format-agnostic

The query language is format-agnostic. Commander players use it most because Commander decks are big and the "what do I already own" question is more painful at 99 cards than at 60. Modern, Pioneer, Pauper, and Legacy players use it for the same reason: bigger collections meet narrower decks, and a search-driven workflow saves time. Search for is:commander to find legendary creatures you own that could lead a deck. Search for t:land f:commander to audit your manabase against a list. The deck-building search adapts to whichever format you're working in.

Get started

Sign up for a free account to use the deck-build search across your collection. Already a member? Log in and run your first query. The search depends on a populated collection, so if you haven't uploaded yours yet, start with the collection tracker or import from Moxfield or Manabox. To extend the search to your friends' cards, join your playgroup's digital trade binder, and once you've found a card someone else owns, send a request through the trade tool. Tracking a specific set? The set completion tracker handles that workflow directly.
