Manamancer keeps a daily price series for every paper printing it indexes, and a local copy of the Scryfall card database that every deck check and search runs against. These articles are what happens when we point those two things at a question instead of at a deck list.
That is the whole editorial standard, and it is a narrow one. A piece runs here when there is something measured to say — a number read off the archive on a stated date, a card text checked against the index, a claim that would change if the data changed. Where a figure is an estimate, it says so in the sentence that carries it. Where we do not have the data, we do not publish the piece.
What you will find here
Set reviews. When a set lands, the interesting question is rarely "what is in it" — the spoiler sites answer that within hours. It is what the reprints did to the printings you already own, which new legends people are actually building rather than theorising about, and whether the preorder price was a real signal or an opening bid. Those are archive questions, and the answers change day to day during a preview window.
Price analysis. Reprints, rotation, banned-list announcements, and Commander-deck reveals all move prices in ways that are easier to argue about than to check. Having two years of daily market prices means we can check.
Commander strategy. The parts of deck building that are countable: how many lands, how many sources of each colour, how much interaction, what a curve actually implies about your opening hand. Manamancer computes these for your own list in the Stats view; an article is where we explain what a good number looks like and why.
How these differ from the guides
The guides are documentation. They explain what Manamancer's own tools measure — what goes into the mana curve, how legality is decided across Commander and thirteen other formats, how the Commander Agent validates every card it proposes. They are reference material, updated when the product changes.
Articles are the opposite: they are about Magic, not about Manamancer, and they go out of date the way news does. A set review is a snapshot of a market that was moving while it was written, which is why every price in one carries the date it was read.
On cadence, honestly
There is no publishing schedule. Writing one of these properly means pulling the series, checking the card text, and being willing to bin the premise when the numbers do not support it — which happens. A thin post published on time is worth less than nothing, so we would rather the shelf stay short.
If you want to be told when something lands, the fastest route is the Manamancer home page, which carries the most recent pieces near the top. Corrections and article ideas both go to the same place: contact.
