Actually there will be a gain I think if you craft the golden ones and you already have the regular ones, because you can dust the golden copies then and make a 800 dust benefit for Ice Block and Molten Giant !

Hey, awesome review as usual ! However I kind of disagree with you about Ragnaros the Lightlord which saw a lot of play after WotOG came out ! It progressively disappeared after we entered the Year of the Mammoth according to me
