Time Spiral Draft Booster Box EV Calculator

Estimate the expected value (EV) of Time Spiral 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.

Original 2006 Time Spiral contains 36 packs of 15 game cards. Every pack has one Timeshifted card across finishes: a premium Timeshifted replaces the nonfoil Timeshifted, while a main-set premium replaces a common. At most one premium appears per pack. The retained community foil probability is 9/40, with individual weights disclosed as assumptions. Draw all 540 cards before Sift or user filters, without reroll or backfill.

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.

Pack Structure

Each Time Spiral Draft Booster Box is modeled with 15 game-card slots.

Foil sheet slots0.225 expected / pack
Pool: 422 modeled card outcomes.Foil sheet slots: 0.225 expected / pack (22.5% expected per pack).
Nonfoil Timeshifted sheet0.971875 expected / pack
Pool: 121 modeled card outcomes.Exactly one Timeshifted across nonfoil and foil finishes in every pack.
Common sheet slots9.803125 expected / pack
Pool: 121 modeled card outcomes.Common sheet slots: 9.803125 expected / pack.
Rare sheet slots1 card / pack
Pool: 80 modeled card outcomes.Rare sheet slots: 1 expected / pack.
Uncommon sheet slots3 cards / pack

Draw all game-card slots first, then apply any Sift or filtering logic afterward.

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

Release-specific model analysis

What drives Time Spiral Booster Box

Product profile. This draft booster box resolves 540 card positions across 824 named outcomes. The model snapshot dated October 16, 2026 contains 242 Common, 242 S, 160 Rare, 160 Uncommon, 20 Basic Land. Its largest slot groups are 422 old foil, 121 old common, 121 old tsts, 80 old rare, 80 old uncommon. Every listed outcome contributes to the published baseline unless the visitor applies a post-draw filter.

Largest modeled weights. Aether Web #189 (2.92 expected per draft booster box), Aetherflame Wall #142 (2.92 expected per draft booster box), Amrou Scout #1 (2.92 expected per draft booster box), Amrou Seekers #2 (2.92 expected per draft booster box), Ancient Grudge #143 (2.92 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. Academy Ruins #269, Akroma, Angel of Wrath (Timeshifted) #1, Ancestral Vision #48, Ashcoat Bear #190, Aspect of Mongoose #191, Auratog (Timeshifted) #2, Celestial Dawn (Timeshifted) #3, Consecrate Land (Timeshifted) #4. 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, 824 modeled outcomes have a usable direct or documented fallback price. The largest deterministic contributions come from Ophidian Eye #70 ($34.62), Gemstone Caverns #274 ($23.44), Spirit Loop #42 ($16.97), Norin the Wary #171 ($9.40), Reiterate #175 ($8.83). Together those five rows account for 22.6% 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.
