Common questions
What rarity is Yamask #99?
Yamask is a Common. Lost Thunder contains 56 cards at that rarity out of 240 total.
Does condition change what Yamask is worth?
The prices on this page are for raw, ungraded copies.

Scryda scans the card, reads the exact print and finish, and shows raw alongside graded comps.
