What's new

Recent improvements to the deckbuilder. Newest changes first.

24 October 2026

Builds learn from ~18,000 more real Commander decks

Commander builds now draw on about 18,000 more real-player Commander decklists when deciding which of your cards belong together, so card choices reflect how the format is played right now.
Deck Search has grown to over 333,000 decks (up from about 315,000) to match against your collection.

23 October 2026

Picking colors no longer empties Commander builds; better stack dealing

Picking colors without a commander could return no decks at all, with no message, when a theme was narrower than your pick (for example a mono-red theme under a blue-red pick). Your picked colors now set the commander's colors, so those builds return decks again.
When a color pick still can't be filled, the build now says why: which color you're short on, or that none of your commanders in those colors fits a theme.
"Fill existing space" now accepts TCGplayer files that list the same card at more than one spot in your stack, and deals each copy at its own position instead of rejecting the file.

20 October 2026

Picking only Colorless builds a colorless deck

Choose Colorless as your only color and the build is now a colorless deck: colorless cards and Wastes only, led by a colorless commander in Commander. Before, that pick was treated as "any colors" and could return a five-color deck.
When your collection can't fill a colorless deck, the build says how far the closest attempt got and how many legal colorless nonland cards you own, so you know what to add.
Colorless together with other colors works as before: those colors set the deck, and colorless cards are always allowed. Picking a colored commander together with Colorless keeps the commander's colors and says so.

14 October 2026

Commander builds explain themselves; fewer builds come back empty

When a Commander build can't start or a filter blocks every deck, it now tells you why. If your collection has no legendary creature (or planeswalker) that can be a commander, you see that straight away instead of an empty result.
Lock a theme and it now gets built whenever the cards are there: the lock wins over the play style you picked, and a theme whose cards are in your collection is no longer dropped before it gets a turn. When a locked theme still can't be built, a notice says what stopped it: it scored below the minimum for your collection, it sits outside your commander's colors, it's a colorless deck that can't meet a multi-color pick, or it doesn't fit the card you required.
Pick colors without a commander and the chosen commander now stays inside those colors. If you own no commander of exactly those colors, the builder uses the closest wider one and tells you, keeping the deck itself in the colors you picked. A required card outside your picked colors is now flagged before the build starts.
Double-faced commanders such as Etali, Primal Conqueror and Esika, God of the Tree now get the same real-deck data as everyone else, so pinning one builds a proper deck instead of falling back to a generic one.
Small collections build their closest-fitting deck, with a note saying how close it came, instead of returning nothing.
After the final round of card swaps, the exported decklist, color breakdown and basic lands always match the cards in the deck. Decks in multi-color builds keep every picked color through those swaps.

12 October 2026

Commander builds start from your commander; color picks mean what they say

Pick a commander and the build now starts from that commander: the cards real decks of that commander actually run, drawn from your collection and kept within its colors. Before, the builder looked for a theme first and a commander second, which left many commander builds with 0 decks.
Choose two or more colors and every deck now uses all of them. Gruul means green and red cards in the deck, not a mono-green deck with a few red lands. Each color you pick gets a real share of the nonland cards.
Every deck now shows its theme (the closest archetype in our catalog) next to the commander in the results, and commander-first decks are marked so you can tell how they were built.

2 October 2026

Big bins show every card

Bins with thousands of cards used to stop partway through the alphabet. They now open with the first 2,000 cards and a Load more button at the bottom to keep going.
Clicking a search result now opens the bin right at that card, even if it's deep in a huge bin. Use Load earlier to see the cards before it.
Editing a card in a big bin keeps your place instead of sending you back to the top.

31 August 2026

Imports can now fill existing space

A new "Fill existing space" option when importing: instead of making a new bin, you get a short dealing plan — "deal 14 cards into bin 31, next 22 into bin 44" — that tops up bins with room, in the order you'd walk your boxes.
Keep your file in the same order as your physical stack and just deal off the top; each stop names the card that should be on top so a miscount is caught immediately.
Nothing is saved until you confirm you've dealt them, and the plan can be downloaded to carry to the shelves.
When your bins run out of room, the leftover cards get new bins named to continue your numbering automatically.

30 August 2026

Inventory edits are instant now

Changing a quantity or moving a card updates the page immediately — no more loading flash or the list jumping while everything re-downloads.
Select several cards with the new checkboxes and move them to another bin in one go.
Moving a card now confirms itself with a small note — and its View button takes you straight to the card in its new bin.
If an edit fails, the message now appears on the row you touched instead of at the top of the page.
Search results and the Sets panel quietly refresh themselves after you edit, so their numbers stay honest.
Renaming or deleting a bin uses a proper dialog that shows what's inside before you commit.

29 August 2026

Faster inventory edits: steppers, undo, smarter bin picker

Every card row now has − and + buttons, so adding or pulling a single copy is one click instead of retyping the quantity.
Removing a card (the × button, or stepping down to zero) now shows an Undo toast for a few seconds — accidental deletes are no longer permanent.
The Move-to bin picker lists bins from the same box first and skips the bin the card is already in, so the right destination is at the top instead of buried under other boxes.
Importing several CSVs in a row now picks up each file's name as the bin — previously only the first file's name was used.

28 August 2026

Clearer builds: visible errors, smoother flow

Build problems now tell you what happened and what to do — rate limits, cooldowns, security-check hiccups, and network errors all show a clear message under the Build button instead of silently stopping.
Cancelling a build now says so, and finished decks scroll into view instead of hiding below the progress bar.
Raising Beam width no longer permanently overwrites your Max decks setting — lower the beam and your value comes back.

16 August 2026

Training data +150%, 60+ new archetypes

Augmented the Commander training dataset by ~150%, which added 60+ archetypes (219 total) and tightened strategy alignment — builds stick closer to how each archetype is actually played.
Deck Search index up 75%, including lists for the newest commanders.
Combo database up 76%.

9 August 2026

Better commander picks + more deck variety

Builds now pick commanders whose abilities matter for the deck, not just ones in the right colors. You'll see fewer generic bodies leading specialized strategies.
More archetypes show up in builds — Zombie tribal, Merfolk tribal, Rakdos sacrifice, and others that were previously squeezed out.

30 July 2026

Fulfillment history for your inventory

Committing a fulfillment now saves it to a new Fulfillment history panel on your Inventory page, so the decks you exported (basics included) and the pick list you pulled are no longer lost when you start another build.
Re-download any past deck as a text list, or the whole pick list as a CSV, straight from history.

30 July 2026

Auto-built decks match your collection better

Building decks without a chosen commander now favors the strategies your collection supports best, and stops building around themes you own only a few cards for.
Themed builds also pull in more of the cards that fit the strategy, so decks stay on-theme.

19 July 2026

Commander builds got smarter

Commander decks now stay on theme: reanimator builds understand reanimation, lifegain builds understand lifegain, and archetypes across the board learned what actually defines them from tens of thousands of real decks.
Obscure filler cards with hidden drawbacks no longer sneak into decks by looking like “ramp” or “card draw” — the builder now checks whether real Commander decks actually play a card before crediting it as a staple. Genuine staples like Sol Ring are unaffected.
The result: auto-built Commander decks come out noticeably more on-theme.

17 July 2026

Sharper Legacy builds

Legacy decks now pick more realistic cards — the builder's card judgment was retrained against real tournament lists, so its builds land closer to decks people actually play.
60-card decks full of playsets now get the complete card-swap optimization pass. Previously, tightly-tuned lists with few unique cards skipped it silently.

16 July 2026

Combo packages + a Commander color fix

Legacy and Pauper builds can now assemble real combo packages — the builder recognizes when your collection holds the pieces of a known combo (think Painter's Servant + Grindstone) and swaps the whole package in when it makes the deck stronger.
Fixed Commander builds sometimes ignoring your commander's colors: a two-color commander could come back leading a colorless artifact deck. Builds now stay on-color.

14 July 2026

Wider deck search + a cleaner set filter for Crew

Crew can now widen the deck search: a new Beam width control under Advanced Parameters explores more candidate decks per build (a little slower, sometimes better results).
The Crew set filter is easier to use — search your sets and add them as Include or Exclude tags instead of scrolling a wall of buttons.

13 July 2026

Set filtering for Crew

Crew members can now build decks only from the sets they choose — or keep certain sets out of the pool entirely. Find it under Advanced Parameters on the build page.
The build form now tells you when a filter can't change anything — like a language filter on an all-English collection — so you never wonder whether a setting is doing something.

13 July 2026

Mixed-language collections now build fully

Pick any combination of languages for a build — or leave the new Languages filter empty to use every card you own. Previously only one language at a time made it into the pool.
Foreign printings (German, Japanese, and more) are now recognized as their English equivalents everywhere: deck building, Deck Search completion, and picklists all count them toward your pool.

11 July 2026

Bigger deck library, smarter archetypes

Deck Search now covers 125,000+ real decks across multiple formats — including Legacy, Pauper, Tiny Leaders, and Pauper Commander lists alongside Commander.
The deck builder learned 80 new Commander strategies straight from real decks — tribal themes like Robots, Snakes, Cats, Frogs, Ninjas and Assassins, plus dozens of play patterns that never had a name before.
Deck exports now include basic lands: the copy-missing list and CSV picklist state exactly how many Plains, Islands, Swamps, Mountains or Forests to add, so an exported deck is complete.
Deck Search gains an “I own the commander” filter, and card previews load instantly from a faster image pipeline.

10 July 2026

Organize your collection your way

Inventory bins now nest into a box / row / bin tree with collapsible sections, and moving or importing cards uses a searchable bin picker that can create new bins on the fly.

3 July 2026

Search real decks from your cards

Browse a library of real Commander decks and instantly see which ones you can build from your collection — each with a completion percentage and an exact breakdown of the cards you're missing. Filter by commander, color identity, or must-include cards to narrow it down.

3 July 2026

Save and organize your collection

Save your collection to the site and organize it into named bins or locations. Browse everything in a sortable pick list and build decks straight from your saved inventory — the builder tracks exactly which cards to pull from each bin.

29 June 2026

Decks that play like the real thing

Auto-built decks in Commander, Brawl, and Pauper Commander now draw on the cards that real decks of your commander actually run — so your builds land more on-theme, especially for commanders that don’t fit a tidy archetype. You’ll see it reflected in a higher Synergy score.

28 June 2026

Honest deck synergy score

The “Synergy” stat on each deck now reflects how much your deck overlaps with real decks of that commander (or format) — instead of always reading near 100%. It’s a truthful read on how on-theme a build actually is, and shows “—” when there isn’t enough real-deck data to judge.

25 June 2026

Smarter automatic deck suggestions

Auto-built decks now span a wider, better-fitting range of strategies for your collection, instead of leaning on the same artifact deck regardless of what you own.
Refreshed the card database to the latest set data, so newly-legal cards are available to the builder.
Marvel's Super Heroes (MSH) cards are now recognized as legal in Commander — they show up as eligible commanders and deck cards where they should.
Fixed double-faced “Battle” cards (e.g. Invasion of Fiora) incorrectly being offered as commanders.
