I'd just use Shak'har's Revenge on it.
I'd win pretty easy, only tough part is the extra ice dragons mixed with the Ulitharids... He might poise a little extra damage and make me think some more than I do vs. Elidnis, or Neptune... but still vs. a voodoo trick, H2O fails pretty bad. Looks very similar to Elidnis tho ... just more water, less life, healing, quint, phase dragons, and Twin Universe... but you added steam machines and 1 steal...
none of your critters are protected... literally, all that rainbow quanta is going to be a waste if the critters can't use their abilities.. the worst one being the 2 ulitharids .. if you can fireball, or lobo them, you pretty much don't have anything to worry about...
The deck needs a combo kill, currently, there is no combo kill at all.. just a mix of water critters, and quantum towers so they can use their abilities... Seems kinda boring imho.
