We do not have the Near Mint average for the English print yet. Meanwhile this is the Cardmarket 30-day average, which mixes every language and condition (updated 07/11/2026).
It exists in several finishes (Normal, Reverse holo). Each one has its own price; the average above is for the regular version.
Artwork by Emi Yoshida. Some collectors chase every card by the same artist: how to start (in Spanish).
