Metagame concentration
How few decks Standard is, month by month, against every ban on record. Each point is the chance that two decks drawn at random from that month's field are the same archetype (the Herfindahl–Hirschman index), shown as the number of decks a field that concentrated is equivalent to. How this is calculated
Lower means more concentrated. Months pooling fewer than 200 classified decks, or fewer than two events, are left blank rather than plotted — below that the reading moves more with how much data the month held than with the format. Decks the classifier could not name are excluded; each point's tooltip reports what share of the field that left.
Tier history — top archetypes
The 8 biggest archetypes by meta share, on one axis. Each line is the score its tier is computed from, so a ban or a set release shows up as the whole field rearranging.
The Y axis is the score each archetype's tier is computed from: for measured points a 60/40 blend of MTGGoldfish meta share and TopDeck top-8 appearances, for reconstructed ones the meta share our classifier derives from standings. Dashed horizontal lines mark the tier thresholds.
Deck costs estimate an average list at each card's cheapest printing across all printings, promos and reprints included.
