Cool. I placed - for the first time, and by a stroke of luck - 16th in my second gold tournament last week, and the prize for 16th was a substantial 6,200 DEC! So i went ahead and purchased a "100% mystery gift" potion, based on the luck you have had recently. Let's see what happens... If I do get a massively high-valued card (like the "Archmage Arius" (Level 1) that you go) I would likely sell it and buy additional 100-pack "Untamed" pre-sale promo sets. The two main reasons for that would be : ( 1 ) I enjoy the process of opening the cards (ex. get some pizza and beer and make an evening of it), and ( 2 ) the sheer number and UTILITY of the cards I would get in the 100-pack promo sets would actually end up being worth MORE in the end, when you consider how much you will use all the gold and legendaries into the future. Yes, of course it's nice to have that lovely "Archmage Arius" in your collection to look at, and you seem to have a bit more $$$ to throw around at the game (all power to you). But for me, who is trying to maximize return on a limited budget, I would go for usability over collectibility at this point. Just my personal opinion...
