Onslaught Draft Booster Box EV Calculator

Estimate the expected value (EV) of Onslaught 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.

One Onslaught display contains 36 fifteen-card packs (540 game cards). Each pack resolves eleven common, three uncommon and one rare position. The English manufacturer box prints approximate premium odds of 1:70 cards; historical premiums replace same-rarity positions, with foil basic lands in the common pool. The retained rarity-specific foil allocation, uniform printing weights and independent eight-variant sheet model are assumptions. Draw the complete product before applying Sift or filters; rejected cards are not rerolled.

Release-specific model analysis

What drives Onslaught Booster Box

Product profile. This draft booster box resolves 540 card positions across 680 named outcomes. The model snapshot dated October 12, 2026 contains 220 Common, 220 Rare, 220 Uncommon, 20 Basic Land. Its largest slot groups are 130 old foil common or basic, 110 old common, 110 old foil rare, 110 old foil uncommon, 110 old rare. Every listed outcome contributes to the published baseline unless the visitor applies a post-draw filter.

Largest modeled weights. Accursed Centaur #123 (3.55 expected per draft booster box), Airborne Aid #62 (3.55 expected per draft booster box), Anurid Murkdiver #124 (3.55 expected per draft booster box), Aphetto Dredging #125 (3.55 expected per draft booster box), Ascending Aven #68 (3.55 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. Aether Charge #184, Aggravated Assault #185, Airdrop Condor #186, Akroma's Vengeance #2, Backslide #70, Barkhide Mauler #246, Akroma's Blessing #1, Ancestor's Prophet #3. 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, 680 modeled outcomes have a usable direct or documented fallback price. The largest deterministic contributions come from Polluted Delta #321 ($42.45), Flooded Strand #316 ($39.66), Wooded Foothills #330 ($38.73), Windswept Heath #328 ($28.73), Bloodstained Mire #313 ($27.69). Together those five rows account for 29.4% 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.
