when the patch went live i lost atleast 10 card in my collection i could find maybe more that i dont know about.not sure what to do for contacting because alot of them helped me get to the rank i was at.
The core set was changed when the patch and the new expansion was released this week.
The core set are those few cards in your collection that can’t be disenchanted. Every year this set is changed and adjusted for the new year.
If you yourself never pulled those missing cards from packs or crafted them yourself then you never owned them. You just got to use them for free for a year as part of the core set.
Here is a list of the cards that were changed:
No I pulled them, a they got straight up deleted it’s mainly cards thay were part of the mini core set rotation. Been playing since alpha
