The odds
Cornerstone Mask Ogerpon ex is a Secret / Rainbow in Twilight Masquerade — the pack's hit slot lands on Secret / Rainbow 2.5% of the time, split across 17 secret / rainbow cards in the set, so pulling this exact card is roughly 1 in 683 packs.
Estimates only. Pack odds come from CardTrack's pack model (the same one behind the pack simulator) — not an official rate. Grading odds are the real cumulative PSA population, which skews toward nicer, resubmitted copies, so it overstates the true first-submission gem rate. Full grade-by-grade breakdown below.
Grade-by-grade ROI & risk-adjusted outcomesNet vs raw per target grade, plus the probability-weighted distribution

⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 998 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 50.5% | $63.00 |
| PSA 9 | 39.1% | $29.00 |
| PSA ≤8 | 10.4% | $15.00 |
Net = graded value − raw value − grading cost (tier fee + ~$20 round-trip shipping), using PSA fees as of 2026-06-28; the paused PSA Value tier is excluded so this isn't overstated. Gem rate is estimated from cumulative PSA population, which skews toward nicer, resubmitted copies — so it overstates the true grade rate. Treat it as a guide, not a guarantee.

Only 51% of 998 PSA-graded Cornerstone Mask Ogerpon ex copies are a gem-mint 10 (504 of 998) — the rest grade lower.
