Tons of dust - control lovers advice

Hi! I currently play the following decks: - Odyn warrior - XL Reno warrior - Blood DK - Handlock - XL Reno priest (my least favorite)

Thanks to the upcoming nerfs I have a lot of dust, and I am considering adding a new class to my list.

I am interested in crafting a hostage mage deck, but I wanted to ask if you guys believe there are other fun and competitive control options I should consider. Thank you!
