With the new update i got 500 wins with paladin and received the golden hero. The achievement also showed a golden Tirion but it is not showing up in my collection.

I guess those are Core set cards and will become available on March 30.

Ah, I see. Thank you!

Did it show up for you? I just got my 500th and already had a golden Tirion, but only one is in my collection.
