Urza's Legacy Draft Booster Box EV Calculator

Estimate the expected value (EV) of Urza's Legacy Booster Box using daily generated TCGplayer price snapshots and the backend draft-box model.

Model assumptions & evidence

This historical model draws all game-card slots first, then applies included-bucket toggles and optional Sift filtering as post-draw scoring filters.

Draw 36 complete fifteen-card packs: each has 11 common, 3 uncommon and 1 rare positions. Foils replace their own rarity. The original 1:100 per-card foil aggregate and all 286 printing/finish marginal weights are retained. The product-specific community recipe couples independent foil events at 11% for the common group, 3% for uncommons and 1% for rares, at most one foil per rarity group and up to three per pack. These are modeling assumptions, not verified factory correlations, sequencing or box guarantees. Draw all 540 cards before Sift or included-pool filters; never reroll or backfill filtered cards.

Value Threshold

Prices load from daily generated TCGplayer, Mana Pool, and Cardmarket snapshots. EV applies Sift after modeled contents are drawn.
Rows with Value >= Sift tint green. EV uses Sift only when the toggle is checked.

Confidence band: -
Each bar groups simulated box totals after modeled contents are drawn, then Sift and included-bucket filters are applied.

Non-game inserts are not counted toward EV unless the model explicitly lists them.

Release-specific model analysis

What drives Urza's Legacy Booster Box

Product profile. This draft booster box resolves 540 card positions across 286 named outcomes. The model snapshot dated June 17, 2026 contains 110 Common, 88 Rare, 88 Uncommon. Its largest slot groups are 55 old common, 55 old common foil, 44 old rare, 44 old rare foil, 44 old uncommon. Every listed outcome contributes to the published baseline unless the visitor applies a post-draw filter.

Largest modeled weights. About Face #73 (7.13 expected per draft booster box), Angelic Curator #1 (7.13 expected per draft booster box), Aura Flux #27 (7.13 expected per draft booster box), Bouncing Beebles #28 (7.13 expected per draft booster box), Burst of Energy #3 (7.13 expected per draft booster box). These are frequency leaders in the product model, not a promise that any individual opening will contain them.

Release-specific card examples. Angel's Trumpet #121, Anthroplasm #25, Archivist #26, Avalanche Riders #74, Cessation #4, Cloud of Faeries #29, Blessed Reversal #2, Defender of Law #5. Seeing the named pool makes it possible to compare this release with adjacent sets instead of treating every sealed product as the same generic pack calculation.

Reference snapshot value concentration. At the TCGplayer Market snapshot dated August 12, 2026, 286 modeled outcomes have a usable direct or documented fallback price. The largest deterministic contributions come from Grim Monolith #126 ($381.49), Deranged Hermit #101 ($71.41), Palinchron #38 ($35.25), Goblin Welder #80 ($32.69), Snap #43 ($30.58). Together those five rows account for 48.4% of the modeled gross value. This dated reference does not update with the live calculator's prices or Sift settings.

The baseline product model is constructed first, including any documented chase exclusions. The calculator then draws the complete baseline product. Included-pool controls and optional Sift evaluate that completed draw afterward and do not alter its collation.
