Evidence disclosures & limitations for Twilight Masquerade
  • No completed-sale observations: prices are marketplace estimates and listings, so every price band is at its widest.
  • The Pokémon Company International does not publish official pull rates; slot weights use TCGplayer multi-thousand-pack empirical opening benchmarks.
  • Card prices resolve from FoilFox printing-level TCGdex normal/holofoil/reverse observations when variant-level observations are absent.
  • Every card in a rarity and finish pool is equally likely; draws are treated as independent.

How FoilFox calculates booster box expected value (EV)

Why mean expected value alone misleads—and how FoilFox models a box.

A single expected value number mixes everyday pulls with 1-in-2,500-pack lottery cards. FoilFox models each booster pack as an explicit slot grammar with mutually exclusive branches, updates pull-rate priors with empirical opening counts using a Beta-Binomial posterior, and runs Monte Carlo box trials alongside parameter-uncertainty scenarios.

Every box shows both its exact arithmetic mean expected value and its median box outcome (P50), 10th–90th percentile spread, chase vs. non-chase expected value split, and probability of clearing the reflective market price.

Collector vs. Seller valuation personas

Collector value prices every pulled card at its realizable FoilFox market quote or labeled estimate. Seller net subtracts 13.25% marketplace fees and $0.15 per-card shipping on cards at or above $1.00, and values sub-dollar bulk at $0.03 per card.

All figures are planning estimates, not a guarantee, appraisal, or offer. Unpriced catalog variants count as $0 rather than borrowing another printing’s price, and every price band widens when completed-sale observations are scarce.
