Let's be honest here: My deck is not very good.
But I just scraped together 1600 dust.
I was going to craft a Bloodmage Thalnos... but I also have no Pyroblast and no Blizzard.
I suppose those would be more useful?
Or maybe an Auctioneer?
I have Cairne, Antonidas, Malygos, Nazdormu (gah), and Illidan.
I also have the "normal sort of stuff" like Kirin Tor Mage and Azure Drakes and Twilight Drakes (I don't have all the secrets though)
I'm not posting a whole deck because whatever I craft next will drastically change my deck.
You will say "Well what kind of deck do you want to play?"
My deck needs work. My deck is not good, and it makes me angry.
But it's sort of aggroish-until-I-get-Antonidas-out and then hope-they-aren't-a-priest.
Basically I like playing Antonidas. He's fun. He doesn't always work, but it's very satisfying when he does. So I am guessing you will say that Gadgetzan Auctioneer and Blizzard might be good to craft with this dust.
But I am asking anyway because I need a second opinion.
And I won't dust the dragon even if it is lame.
