The stock list, and how firmly each slot is held

75 slots, shaded by how many decks hold them

Every card copy in the stock list gets one tile, grouped by card, with the average copies across the field printed after the name. A tile goes dark when nearly every deck plays at least that many copies, and heats up towards red as the field thins out — the ember tiles are the slots actually being argued over. Cards that miss the stock list but that a real slice of the field still plays are drawn after it in dashed outlines: slots competing to get in, rather than slots being defended.

Every deck as a difference from the stock list

The modal deck, month by month

Average copies per deck, month by month. The modal list rounds these to whole cards and so sits still; the averages underneath it do not. Biggest swing first.

The variants as a map

Every list registered, one row each

One row per distinct list, most-played first, with the number of decks that registered exactly it on the left. Columns are the cards anyone changed and each cell carries that list's actual number of copies: warm when it runs more than the stock list, cool when it runs fewer, faded when it agrees.

How many cards you would have to change

Distance is the number of card slots between a deck and the stock list — swap one Mountain for one Faithless Looting and you are at 1.

Every deck in the sample

All lists, newest first. The player name opens the deck on MTGGoldfish; the event opens the official decklist page on mtgo.com. Δ is the number of cards between that deck and the stock list.
