⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 188 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 38.3% | $83.00 |
| PSA 9 | 39.4% | $33.00 |
| PSA ≤8 | 22.3% | $11.00 |
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.

Card text
This card stays in play after being played. Discard this card if another Stadium card comes into play.
Whenever a player plays a Trainer card other than a Stadium card, he or she flips a coin. If heads, that player plays that card normally. If tails, the player can't play that card. If the card isn't put into play, the player's opponent may use that card instead, if he or she does everything required in order to play that card (like discarding cards). Either way, the card goes to its owner's discard pile.
