Expected hits per product: 5.52 (counting every tier the pull-rate table enumerates). The Bulk / regular cards row is the rest of a pack — commons, uncommons and plain rares worth about a cent — shown so the odds add up to the whole pack.

Same assumptions as the EV: odds are uniform within each tier (real sets short-print their biggest chases, so true odds are usually a touch worse than this), cards sell at today's market price, and selling costs nothing. Read it as a ceiling, not a promise.

Each tile: card value (top-right), then the odds of pulling that exact cardfrom a single pack — shown as “1 in N packs” and as a percentage (the same number, two ways). Per-card odds assume every card in a tier is equally likely — no public data quantifies short prints. See methodology.

Is it worth grading?

PSA US fees, approx · Jul 2026

What a PSA 10 sells for vs the raw price plus PSA's fee — the upside if the card grades a 10. The odds of actually getting a 10 are a separate column, still pending.

Net if 10= PSA 10 value − raw − fee, the gain assuming a perfect grade (an upper bound — most cards won't 10). Chance of 10is this card's own PSA population — of every copy graded, the share that came back a 10 — and it drives the graded EV toggle instead of one flat assumption. Read it as a ceiling, not a coin flip: it counts cards people CHOSE to submit, which skews toward good copies, and a card pulled from a pack today may fare worse. A “—” means too few graded copies to quote. PSA 10 prices come from Scrydex and PokemonPriceTracker. Fees exclude shipping and use the cheapest PSA tier for each card's declared (graded) value. PSA paused its cheaper Value tiers in June 2026 under a grading backlog, so Regular ($79.99) is the current floor — grading a card much under ~$100 rarely makes sense.

How many packs for…

295 packs for a 50% chance
978 packs for a 90% chance

No number of packs guarantees it — that is what a -46.4% market ROI pays for.

Pull-rate data

MEDIUMn=20,000source ↗

MEGAドリームex: High Class style box, 10 packs. DIRECTLY MEASURED by pokemon-infomation.com across 2,000 aggregated boxes: 3 AR guaranteed/box; 1 Mega Attack Rare guaranteed/box; 1 Trainer SR guaranteed/box plus ~10% for a Pokemon SR (1.10 SR total); SAR ~40%/box; MUR ~2%/box. Mirror-print variants are print styles, not tiers, and are not modelled. Guarantees are folded into the rates, not modelled as floors, so single-pack products price at exactly box/packs.

  • ! Pull-rate table lists rarity "mega_attack_rare" but the set has no cards of that rarity.
