Maybe I am not getting a joke here, but Nemsy is free for everyone for a limited time: https://www.hearthstonetopdecks.com/nemsy-necrofizzle-warlock-alternative-hero-available-for-free-for-limited-time/

Just to confirm that: I play since late beta days, never climbed above Rank 20, but have no golden hero also. For certain am on a very layman level, meaning that mostly I play my deck, without considering the possible plays of my opponent. HS is my go to game for short burst when I just have the time for that. If I have more time for gaming, I play sth. different. Very happy with the random Tavern Brawls, since there experience counts for much more, its not about knowing your ins and outs for certain matchups. BG was heavensent in that regard also. Arena is ok, but to be really good, you’d have to know more about the meta, which would be time consuming.
So, I play to have fun. Sometimes that can be found in constructed with a fun to play deck. Never cared about climbing enough to put the time in.

“Whenever you play a minion, you cast a random spell of the same cost. E.g. when playing a 1-drop, you get a random 1 mana spell from any class.”
“Cast” is not entirely correct, as you can see on the chalkboard. You get a spell of the same cost, which is then reduced to zero, into your hand.

I always think Twilight Hammer when I see purple in WoW. But the banner is too orderly, and the steel component is missing.

BUT the RoS Crystal does look different, while SoD and next Xpac-Crystal are the same, recolored.
