You could also take one of each and throw in Ragnaros for a solid late game. Druids of the Claw and drakes usually bait out at least 1 hard removal spell, freeing up your ancients and then Rag.
Ancient of Lore has that beautiful card draw that you lack from not having Nourish, and the heal is fantastic against aggro rush decks.
Ancient of War is an absolute beast if they opponent doesn't have a hard removal spell to deal with him. He's a much riskier play than Ancient of Lore but unless you're unbelievably far behind on the board, you will win if they don't have hard removal.
I have Ysera, Cenarius and Thalnos but no Rag or Black Knight yet. I am gonna build Skaith's new deck but will be short the Black Knight so i am putting in Thalnos like you suggested in that thread as well as dropping the Crusader and second Ooze for a couple of Yetis. Will report how it works out.
Crushing cards now for an Ancient of Lore.
