Hi, I have Young Priestess card available in my collection and I saw people playing it against me in classic mode. But when I try to add it to my classic hero, it is not available. How is this possible?
There are two versions of the card, Core and Classic/Legacy. The Core version cannot be played in Classic format.
Interesting, how come some people have it in classic and some only in core? The stats are the same.
All players that have met the minimum level requirements have the Core version, and that version is uncraftable. The Classic version came from packs or was crafted with dust.
More information on the Core set can be found here: https://hearthstone.fandom.com/wiki/Core
