Lookalikes & traps
Promo stamps and prerelease marks sit beside Secret Lair Promo art. Confirm the promo set code rather than assuming booster-pack SLP. Also watch foil vs nonfoil: sheen does not change which set Secret Lair Promo is.
Confirm after the icon
Bottom information line should show collector number + set code SLP (and usually a C/U/R/M rarity letter). On Secret Lair Promo / Lightning Bolt, mismatch between listing title and SLP is the usual bait-and-switch.
How to identify Secret Lair Promo cards
- 1
Start with the Secret Lair Promo glyph silhouette; art style alone will not separate this promo product from guests and remasters.
- 2
Read rarity from symbol color on Secret Lair Promo: black common, silver uncommon, gold rare, orange mythic — foil sheen does not change it.
- 3
Confirm set code SLP and the collector number on the information line under the text box.
- 4
Finish with a Tappr scan when Secret Lair Promo / Lightning Bolt appears under multiple set codes in the same lot.
Rarity by symbol color
Special product (promo): rarity color may still follow modern conventions when a symbol is present, but SKU/treatment beats draft-rarity folklore. Verify SLP and the collector number before comparing to a main-set printing of Secret Lair Promo.
Legend shows the modern post-Exodus palette. Pre-Exodus sets and special rarities (for example Time Spiral purple timeshifted) follow the rarity reading above — not this swatch row alone.
