I’d be happy enough if they restricted it to golden versions: you don’t get triples of golden cards (i.e. you can open a third Warleader if you have two regulars and one golden, but if you have two golden versions of a given card you can’t get a third golden version).
In other words, if you craft a golden card, you don’t risk having the craft be for nothing a month later.
Not to say it wouldn’t be awesome if they did it for epics, but relatively recently a Blue stated in an AMA that there were (paraphrased) “no plans to extend the no duplicates rule to epics”
Divine Hyhm (Priest Common) Good.
Lost Spirit (Neutral Common) Dusted.
Crowd Roaster (Neutral Epic) Ok lol.
Fancy Cardback I really liked this months.
An 10 dust for rank 4.
Overall quite happy. Only 1 dud card. An the epic I didn’t have any copies. Plus its a Dragon… an the next expansion is nothing but Dragons basically lol.
Treespeaker-yay! only had one of these and am currently missing a bunch of Druid Epics, actually want to build a Treant deck!
Soul of the Murloc- eh! Great if I want to annoy everyone by playing aggro Shaman for the last few days before expansion (but I don’t, no more Shaman please!), and lots of nice shiny Murloc tokens I guess.
Spectral Cutlass (finally, been wanting forever to get a copy of this)
EVIL Miscreant (5/5 card, disenchanted my other gold one back when it got nerfed)
Hunter weapon that summons a 1/1 locust with rush upon attacking.
In regards to gold rewards, this has been one of the best ones in a while.
