Grading Summary
This Mewtwo promo shows strong overall condition with only minor corner, edge, and surface flaws. Centering is solid, and the most notable issues are small white nicks and chips around the back corners and front upper edge.
Flags
Image Quality
Strong circular light reflection on the left side of the artwork; it could interfere with surface and corner inspection.
2 back-side defects ignored due to scan quality.
Low-confidence card geometry detected (confidence 0.76, detected sides 1).

Four-axis score profile
Centering is strong overall, with the back appearing nearly balanced left-to-right and top-to-bottom. The front shows a mild vertical bias, but not enough to move it out of a strong centering result.
The corners show only minor wear, led by small white nicks/chips at the back corners. Two additional back-corner defects were observed but were excluded from scoring because the scan quality in those regions was unreliable.
Observed
Edge wear is limited to small white chips/whitening along the front upper cut edge, with no meaningful edge issues elsewhere. The wear is minor but visible enough to keep this component below pristine.
Observed
Surface condition is strong, with only a small chip-like white mark on the lower-right printed border. Front glare affected inspection somewhat, but the observed surface defect is minor and localized.

What's holding this card back
Lowest axisEdges (8.0) is the lowest of the four axes. It's the main thing keeping this card from a higher grade.
The limiting defect is Edge Wear (minor, front).
Bringing edges up to the level of the next-weakest axis (Centering, 9.0) would be the single biggest improvement available.
