⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 88 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 10.2% | $71.00 |
| PSA 9 | 54.5% | $46.00 |
| PSA ≤8 | 35.2% | $20.00 |
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.

This card stays in play when you play it. Discard this card if another Stadium card comes into play.
Once during each player's turn (before he or she attacks), if that player has an Evolution card in his or her hand, he or she may search his or her deck for a basic Energy card, show it to his or her opponent, and put it into his or her hand. Then that player chooses an Evolution card from his or her hand, shows it to his or her opponent, and puts it into his or her deck. That player shuffles his or her deck afterward.
