The Rip Test: The Blue Core Line (Last Resort)
Tearing a card reveals its inner core. Genuine cards show a distinctive blue-black line; this destroys the card, so it is only for worthless commons.
Achtung: This permanently destroys the card. Never rip a card you do not own or one with any value.
Was dieser Test prüft
The inner core layer between the two paper faces, which is blue-black on genuine cards.

Echt sieht so aus
A clear blue-black line running through the middle of the torn edge.
Fälschung sieht so aus
No blue line, a grey or white core, or a single solid layer instead of the layered structure.
Schritt für Schritt
- 1Only ever do this on a bulk common you are willing to destroy.
- 2Tear the card across one corner.
- 3Look at the torn edge from the side.
- 4Check for a blue-black core line between the paper layers.
- 5Use what you learn to calibrate the non-destructive light test.
Warum es wichtig ist
Definitive proof of the core layer — but it destroys the card. Use it to learn, then rely on the light test for valuable cards.
