I'm missing 13 GvG cards and 18 Classic cards, with around 2,000 dust so I can make 1 legendary and 1 epic of my choosing.
What a bummer, I crafted Edwin last week, and I just unpacked him with the pack I got from questing today.
I also have a Golden Lord Jar, and the regular version. If I disenchant the golden one, I could still use the normal one and craft a legendary of my choice, but golden jarax is so nice because it's an animated hero portrait and it makes golden infernals...
