Some cards were nerfed, but we didn’t get full dust refund for them:
Trolley Problem
Odyn, Prime Designate
Asvedon, the Grandshield
[Hearthstone] The Tram Cars summoned by Trolley Problem and Tram Conductor Gerry are no longer Mechs (they don’t have a CPU).
[Hearthstone] Odyn, Prime Designate’s Battlecry effect can no longer be stacked if played multiple times.
[Hearthstone] Asvedon, the Grandshield will no longer spoil secrets.
I mean, that’s not really how it works. If I have a card (a physical card) and someone comes along and scribbles out some of the text on my card…You’re damn right I’m going to be asking/having/making the person who ruined my card give me whatever I paid for the card (or be taken to small claims court). It doesn’t matter how much it was utilized or not.
