Mega Evolution
Sealed product EV calculator

Compare the expected value (EV) of supported Mega Evolution sealed products in one calculator. Choose Booster Box / Display, Elite Trainer Box, or Booster Bundle; the calculator uses the selected product's pack quantity and generated model while retaining the set's documented pull assumptions and live singles pricing.

Promos, energy/token inserts, and Mega Hyper Rare (MHR) cards are not included in this calculation.

Calculation order: every pack's full card contents are drawn first. Disabled pools and optional Sift filtering apply only afterward and never backfill removed outcomes.

Set theme: Mega Evolution is themed around powerful returning Mega forms and premium rarity chase cards, with pull structures tuned to reflect the set's collector-forward identity.

36 packs / booster box Model defaults calibrated against TCGplayer Mega Evolution pull-rate guidance Base slots: 4 Common • 3 Uncommon • 1 Rare-or-better (per-rarity upgrade rates) Premium slot: Ultra Rare, Illustration Rare, SIR, or foil C/U/R Rare and premium rare rows use live foil pricing by default Double Rare, Ultra Rare, and Illustration Rare are modeled as separate pools

Mega Evolution pull-rate context (community estimates)

This calculator uses live pricing with a configurable pack model. Community pull-rate references are listed below for context and validated against the TCGplayer Mega Evolution pull-rate article. Mega Hyper Rare (MHR) cards are intentionally excluded from EV totals in this tool.

Simulation order: card contents are drawn first, then optional Sift filtering is applied to the drawn pulls.

Mega Evolution sample pull-rate assumptions used by the default model.

Double Rare20.91% (~1 in 5 packs)Separate rare-slot branch = 20.91%
Ultra Rare8.23% (~1 in 12 packs)Separate premium-slot branch = 8.23%
Illustration Rare (IR)10.89% (~1 in 9 packs)Separate premium-slot branch = 10.89%

Validation target source: TCGplayer — Pokémon TCG Mega Evolution Pull Rates. Defaults are tuned to this range and can be adjusted if market behavior shifts.

Included pools ▶
Sift is a price floor (USD): rows with Value ≥ Sift tint green. EV only uses Sift if you enable the toggle below, and it is applied after each pack’s cards are drawn.

Selling Fees

Per‑row shows combined pct + txn (txn = 2.5% processing). $0.30/order is added only in the summary.

Value Threshold

Changing this can materially lower EV if Market prices are stale. "Min" uses the lower of Market and Low.
Example: 0.25 removes any card valued under $0.25 from EV only if the toggle is on. Sift is applied after each pack is drawn.

EV Range (Monte Carlo)

Runs per summary update; higher counts smooth the bands but take longer.
Low/High = central quantiles measured from Monte Carlo pack openings.

Simulation Results (after Sift)

Confidence band: —
Each bar groups simulated box totals after cards are drawn, then Sift is applied to pack hits. X-axis = box value, Y-axis = number of simulations in that range.
