It's 2026, July 23. Daily deals, single card offer; Liliana, Dreadhorde General is showing "Collected:0" when I have 4 collected.
I have the tempting option to buy this card for the one-time, bargain price of 800 gems or 5280 gold, over 4-5x the price of a booster, and NOT add it to my collection.
If someone actually clicks this, believing they 0 as displayed, forgetting that they have a set of 4 already, they have no way of proving that fact after the purchase, and they themselves can't be sure how much they really had before buying, as they'll still just see 4 in collection.
This wouldn't be a nice way to do business, were this not a bug.
