Hi, yes it's another Nat Pagle Card D/E from a relative noob to gaming. I have played him for the past 2 weeks or so. And at best he helped me win maybe 2 games I play between 5-10 a night.  I currently have a few legendaries.. Antonidas, VanCleef, Grommash, Leeroy, Black Knight, Ragnaros, and I enjoy playing mostly Mage, Rogue, and Warrior.  I was thinking that Thalnos is consistent and would help mostly in Mage and Rogue decks. I have 1900 dust and thus far the only card I crafted was an Azure Drake so I could have 2.  I was considering keeping him and I guess I'm on the fence about that. I won him in a pack and I don't see myself crafting him again. Yet I didn't want to miss this opportunity of disenchanting him at full cost.  I would prefer to use my dust crafting rare's etc. to flesh out my Mage, Rogue and Warrior Decks. Namely another SI7 Agent,  for example 2 Frothing Berserkers. Any help or advice would be appreciated.

Thanks in advance for your time.

Cairne for sure. 

Cairne is probably the best neutral legendary because of his ability to go in most decks
