Also the new Ancient of Lore is awful. For 7 mana, you don't want your card to be roughly as good as Warlock's Hero Power combined with a good but not amazing 4-drop. You also don't want it to be almost strictly worse than Guardian of Kings. The versatility probably isn't worth it either.
It's pretty much worse than Floating Watcher. For 7 mana, Warlock can use hero power and get a 6/6 Floating Watcher that is dangerous to ignore. Yeah Floating Watcher can't heal, but you can cheat it out with Voidcaller.
I feel like AoL would still be oppressive at 6 mana in this new form. Choose between a slightly worse Shieldmaiden or a slightly worse Azure Drake, two elite cards, might have been a bit much. Same deal with a 7 mana 6/6. Probably the best way to balance the card would be to improve the healing option.
Edit: oh yeah, probably AoL wouldn't have been nearly so oppressive if it weren't for the SR-FoN Combo that it helped you draw into.
