Meta methodology
What's counted
One population per set and per circuit. Majors is every canonical tournament deck from large public tournament results (average field 181 players). Online is every deck from tournaments reported on play.limitlesstcg.com, which are mostly online locals (typically around a dozen players) plus some in-person store events. The two are never combined: each number belongs to exactly one circuit. A tournament covered by both communities is counted once in each circuit, which is what each circuit measures — the two are never added together.
Tiers (ranked by meta-share)
Archetypes are ranked by their share of the population, not by performance: S ≥ 10%, A 5–10%, B 2–5%, otherwise Fringe. Unlabeled/unclassified decks fall into an Other bucket that counts toward the sample but gets no tier row.
Sample size & the n-floor
Every view shows its sample size n. Below 8 decks for a set we withhold the tier list and show an insufficient-data notice instead (the underlying values are still computed).
Performance, shown alongside
We show average placing, 1st-place count, top-8 count, and top-cut share (an archetype's % of the set's top-8 decks). We deliberately do not publish a “conversion %”: the corpus skews to top finishers and has no reliable total-entries denominator, so a conversion rate would be misleading.
Attribution
Every imported deck is attributed to its source tournament. Price-to-build multiplies each card's count by its latest market price (cheapest print).
