Log this decision:

Verdict is computed transparently from indexed pulls: cash-out ROI, median pull, 7-day trend, hit rate, and sample size. Redemption shipping (typically $16+) is not included — cards worth less than a few times the shipping cost are usually better instant-sold than shipped. Not financial advice.

02 / Pool signals

What's happening in the One Piece Master Pack pool

Lifecycle stage, health, and chase removals — read from indexed pulls, never guessed.

Recent pulls are running above the lifetime average (EV +-3% over 7 days) — the pool is trending up without a restock-sized jump.

IMPROVING

Recent pulls are running above the lifetime average (EV +-3% over 7 days) — the pool is trending up without a restock-sized jump.

Pro adds the Pool Health score and chase-removal impact.

Not observable: packs remaining, value remaining, and which chases are still in the pool — Courtyard publishes a pull feed, not inventory. We label those unavailable rather than estimate them. Everything above is computed from indexed pulls and EV snapshots; thin or stale data pulls the score toward neutral. Formula

Chase tracker

chase tier ≥ $500 · confidence 93%

No chase-tier pulls (≥ $500) observed in the last 30 days.

Removals are facts; what's left is not. Each row is a unique graded card observed leaving this pack, so it is no longer in the pool — though a card can return after a buyback, which is why re-listings are flagged. We show no “chance it remains”: Courtyard publishes pulls, not inventory, so that number would be guesswork. Formula

Signal lifetime

SIGNAL Invalidated · 26 h ago

Re-check before acting: the price moved after the newest pull we indexed.

The pack price changed after the most recent pull, so every EV-vs-price call here predates the current ticket.

Half-life: Pro

Aged, not predicted. Half-life counts how fast new evidence arrives, measured from real pull timestamps — it is not a forecast of where EV is heading. We publish no EV-drift half-life because our snapshot history is too short and its early stretch is seeded placeholder data; a number regressed from that would describe our seed script, not the market. Note the headline EV is decay-weighted, so it reacts to new pulls sooner than this whole-sample horizon implies. Methodology

04 / Floor safety

One Piece Master Pack floor safety & buyback reality

The two ways average EV lies to you — how top-heavy the pack is, and what FMV actually converts to in cash — then which exit pays most.

In One Piece Master Pack, the top 2% of pulls account for 6% of all pulled value — low dilution. Value is spread fairly evenly across the pool, so the average is close to what a typical rip returns. The observed instant-offer ratio is 85% of FMV, which is the cash number every verdict on this page already uses.

Floor safety

low dilution

6% of everything this pack has paid out came from just the top 2% of pulls. Value is spread broadly across pulls — the average EV is a fair picture of a typical rip.

Buyback reality

84.6% of FMV observed

Across offers we've indexed, a $100 FMV pull cashes out around $85 if you instant-sell — below the advertised ~90%, so FMV is not your exit price. Every number in our verdicts already uses this haircut.

Holding, listing, or physically redeeming can beat the instant offer — but redemption shipping (typically $16+) eats small wins.

Net exit value

70 paired pulls · 97% bid coverage · confidence 92%

Instant-selling a typical pull here returns $84.38 — $15.36 below sticker FMV (15.4% haircut). That figure is the average of bids we actually recorded, not an assumed 90%.

Pro compares all three exits side by side, with the redemption breakeven and the value-by-value haircut curve for this pack.

Bids are recorded, resale is not. Instant-buyback figures are real offers captured at index time and can move. Redemption shipping starts near $16 in the US, is higher internationally, and is charged per shipment — batching pulls lowers it. We publish no resale estimate, liquidity score, or time-to-sell, because no such data is available to us. How buyback works
