[BUG] Missing Cards from Path of Arthas Mini-Set

Bug Report
1

Hello,

I recently returned to Hearthstone after some time away and noticed a serious issue with my collection. I purchased the Path of Arthas Mini-Set with real money, which includes 28 cards, and I clearly remember playing with several of them — including Overseer Frigidara.

However, upon checking my collection in Wild mode, I noticed that multiple cards from the mini-set are missing. Notably:
• Overseer Frigidara (Legendary)
• Patchwerk (Legendary)

These cards do not appear in my collection as owned — instead, they are marked as craftable with dust, which is unacceptable considering I paid for the entire mini-set. This is not just a display issue — I am actually unable to use these cards in my decks.

I have double-checked:
• I am filtering correctly (Wild mode, no special filters)
• I am logged into the correct account
• I did not disenchant these cards manually

I also reviewed forum threads and found that other players are reporting similar issues, especially after the rotation of the Core Set. This leads me to believe this is a bug affecting players who bought Path of Arthas and are now missing cards they should permanently own.

This is deeply frustrating. How can I trust buying anything again if cards I paid for just disappear?

Please escalate and resolve this as soon as possible. I’m considering bringing this issue to wider attention in other community spaces if this isn’t addressed.

Thank you,

Those cards were not part of the mini-set. They were brand-new additions to the Core set.

Do you know what the Core set is?

It is a large group of cards that Blizzard loans to everyone for free. The cards appear as part of your collection.

However, you do not own them. They are on temporary loan from Blizzard. Each year Blizzard updates the Core set, adding some cards and removing others, to keep the set fresh and interesting.

That is what happened to those two cards (and many more). They were loaned to you as part of Core, but then they were removed in a yearly update.

Again, you did not pay for those particular cards.

Those death knight cards, and many more, were added to Core at the same time the Path of Arthas set was introduced, so that might explain why you thought they were part of that set.

The Path of Arthas set was actually fairly small, only 26 cards.
