09Card Moves and Abilities

10Grading and Population

PSA 10 estimate: Modern Common/Uncommon — most copies are not graded because raw value rarely justifies the fee.

Graded populations stay low; usually collected raw or sleeved rather than slabbed.

Other graders: Negligible BGS/CGC submission volume.
