So...My opponent playeed Queen Azshara and then played Tidestone of Golganneth (the one that puts 5 spells in your deck). I played Vanessa VanCleef and got nothing...not the Queen or the Tidestone.
I don't know if this is a known bug or something else happened (my oponent left at some point while this was happening although I didn't know till the following turn), but I thought I would raise it in case it makes you lose a game.

That is all!
You sure you activated combo. If yes than indeed that's a bug, report to blizzard.
Now that you mention it....maybe I didn't. I don't have any way to check so maybe that's all it was :(
If you are running the deck tracker, you can check the replay.
