UR tempo ascension

first try for my new legacy deck, i use boomerang hoodwink wasteland and stifle trickbind to heavily disrupt my opponents mana, while either building up an ascension which will kill my opponent through lightning bolt time spiral or setting up a dreadnought stifle combo im currently using impulse because of its superiority when copied with ascension and its resistance to mental misstep. in the sb youll find flusterstorm against high tide ad nauseam, dominate is here as a try out since it works well when copied by the ascension and can hit all important creatures at cc=2. the other cards are pretty generic and will more likely be replaced by other cards. let me know what you think...
