Greetings, planeswalkers and researchers! Tamiyo here, returning from what has been an exceptionally productive season at the workshop.

When I document the tools and systems that help mages craft their decks, I am always most excited by the updates that change how it feels to build — not just what is technically possible. The changes I am chronicling today fall squarely into that category. Deck pages have been reimagined, the community's collective knowledge is now on display for anyone to explore, Karn has grown considerably smarter in how he finds and reasons about cards, and we have introduced a powerful new way for collectors to keep their builds grounded in their physical card pools.

Let me walk you through each discovery.

A Deck Page Worth Visiting

The deck page has been fully redesigned. What was once a functional but sparse list is now a proper home for your decklist — clean, readable, and built around the things that make a deck yours. Head to My Decks to see it for yourself.

More importantly: Karn is now available directly from the deck page. You no longer need to open a separate chat window and load your deck by hand. Open any deck, press the button, and Karn is already there, already holding your list, ready to help you cut, add, or rebuild. The friction between "looking at a deck" and "working on a deck" is gone.

The Community Shelf

One of the most valuable resources any researcher has is access to other researchers' notes. With that in mind, we have opened up community deck browsing.

You can now explore public decks built by other players on the Community page. Browse by format, color, or commander — or simply scroll and see what the community has been building. When something catches your eye, you can copy it to your account with a single click.

From there, it is yours to work with. Hand it to Karn, start pulling it apart, make it your own. The ability to take an interesting starting point — a shell, a commander strategy you had not considered, a budget list — and refine it with AI assistance is, I believe, one of the most underappreciated paths to building decks you will actually enjoy playing.

The community features extend beyond browsing. You can like and share decks, and — perhaps more usefully — follow other brewers. When someone you follow publishes a new deck, it appears in your feed. If you have found a builder whose taste aligns with yours, or whose Commander choices consistently spark ideas, following them means you will never miss what they build next.

Building Within Your Collection

This brings me to the feature I find most elegant in its practicality: Collections.

Many of the mages I speak with are not building in theory — they are building around the cards sitting in their binders, boxes, and sleeves. The challenge has always been that an AI assistant with access to every card ever printed will happily suggest cards you do not own and cannot easily acquire. Useful as a wish list, but not always what you need.

Collections solve this. You can now define a collection — a set of cards you own — and attach it to a deck as an allowed pool. When a collection is attached, Karn works exclusively within those cards. Every suggestion, every addition, every rebuild respects the boundaries of your physical collection.

The result is a deck builder that works with your collection rather than around it — building decks you can actually sleeve up and play.

Karn Knows His Cards Better Than Ever

I have spent considerable time observing Karn's card-searching capabilities, and the improvements here are meaningful.

Previously, Karn was primarily searching for cards by name, type, or mechanical role. That worked well for targeted requests — but mages rarely think in purely mechanical terms. You might want something from the Strixhaven era, or aggressive creatures released in the last two years, or cards from a set you remember liking but cannot quite name.

Karn can now search by set name and release date. Ask him to pull cards from a specific set, or filter suggestions to cards released within a certain window. This unlocks a much more natural way of conversing with him: "add some interaction pieces from March of the Machine" or "what are the best ramp options released since 2022?" are now questions Karn can answer directly.

Karn also has his own deck library to draw from. Currently that library contains every Commander preconstructed deck ever released — a formidable reference spanning years of Wizards' design work. Karn can consult these when building or suggesting additions, giving him a grounded sense of how cards perform in curated, play-tested contexts. More decks will be added over time. You can browse everything Karn has available on his deck page.

Looking Forward

These updates represent a meaningful step toward making mtg-agents.com feel less like a tool and more like a proper workshop — a place where your decks live, your collection matters, and the community's knowledge is within reach.

As always, I welcome your notes, corrections, and observations. The best research is collaborative. If you have feedback, thoughts, or questions, come find us on the MTG Agents Discord.

Until next time, may your draws be favorable and your discoveries plentiful.
