I am a total lowbie scrub who sucks ass and evenmycollection is better than Slip's! Seriously though it's funny that he has no Mech Bear Cats at all, whereas I think I've opened a total of like 4 Golden ones on top of 2 or 3 regulars.
I have a Golden Hogger and Confessor. I really should nuke them but I don't have any pressing needs for card atm.
I will say I remember a few times how difficult it can be to craft the second version of an odd Epic. For instance I wanted to play with that super slow control Shaman that requires 2 Elemental Destructions. It's hard to part with that dust right there. Same for when I crafted both Preparations back when I thought Rogue was fun. I mean crafting an Ancient of Lore is easy, but making yourself craft, like, asecondNaga Sea Witch can be cringe worthy.
And yeah for the new guy, some of the first cards you craft should be strong Classic rares like Knife Juggler, Azure Drake, Defender of Argus, or Argent Commander. Knife Juggler is a god-tier card.
