Discover how to surface your most played decks from scattered date columns

Tracking down your most recently played decks across multiple date columns is a challenge Excel can handle, but it requires a smarter approach than a simple formula.

There's a quiet frustration that lives in every spreadsheet user who has ever hit the wall of a question that feels simple but turns out to be structurally awkward. That's exactly where the Magic: The Gathering player in this story finds themselves. They have a workbook tracking each deck they play, with date columns scattered across sections, and they want a top-ten list of the most recently played decks. On its face, that sounds like a filter. In practice, it's a data-shape problem. The dates aren't in one tidy column; they're spread out like a deck after a shuffle. And Excel, for all its power, doesn't naturally think in terms of "look across every column and rank the latest values."

This is the moment where most people either give up, flatten the data manually, or ask for a macro that does one very specific thing. But the underlying issue isn't about Magic: The Gathering, and it isn't even about Excel. It's about how we think about data that wasn't designed for analysis. The user's real ask is not just "find the top ten dates." It's "help me see the pattern in my own behavior without rebuilding my entire tracking system." That's a universal need. It's the same reason we see tools like Explore the Forrester Function: Beyond Mathematics, a Tool for Machine Learning gaining traction, because the value isn't in the raw function, it's in what you can do when you stop forcing data into familiar shapes and start asking what structure actually serves the question.

What this player needs is not a more complex formula, but a mental model shift. Instead of trying to make Excel scan across multiple columns, the cleanest move is to restructure the data into a single column of dates with a corresponding deck name. That's not a workaround; it's the correct foundation. Once the data is in a tidy format, the top-ten most recent decks becomes a simple sort and filter. But here's the honest take: telling someone to restructure their data is easy. Doing it after months of manual entry is hard. That's why the real lesson here is about designing for analysis from the start. It's the same principle we see in Improve Crop Yields with Automated Soil Aeration—No Robots Needed, where the innovation isn't in adding complexity but in removing friction. The pod doesn't do more work; it changes the conditions so the work becomes easier.

The better path forward for this user is to embrace a small amount of upfront change for a long-term gain. Use a single "Date Played" column and a "Deck Name" column. Log every game as a new row. Then, the top-ten question answers itself with a simple sort. If they want to keep the current layout, they can still use a helper column that pulls the latest date from each section and then rank those. But that's a patch, not a solution. What we'd tell anyone who asks this question is to stop optimizing for the way you've always tracked data and start optimizing for the way you want to use it. The decklist isn't the problem. The structure is. And the fix is simpler than it feels, but it requires letting go of the old layout. That's the trade-off. Are you tracking data to have it, or to use it? Because the moment you answer that, the spreadsheet stops being a storage space and starts being a tool. And that's the real win. Watch whether this player makes the jump to a cleaner structure, or whether they keep fighting the tool instead of changing the frame.

I play a lot of Magic: The Gathering. I have a spreadsheet that tracks when I play each of my decks and the outcome of the game. The spreadsheet has a section for each deck, and then a column of dates for when I played those decks.
