U/W Control

this is the new u w control. please give me suggestions's because i am trying to perfect it. the darksteel additions to thew deck are pulse of the fields and panoptic mirror. let me give an explanation for pulse of the fields. pulse of the fields abuses every beatdown deck. it allows you to play lands and gain card advatage but not take damage. then when you opponent can start doing larger amounts you wrath of vengeance away. the reason i am not playing exalted angle it because it does not go with synergy of the deck. first, it is a creature so all you removal spells kill it except for oblivion stone it your angel has a fate counter on it. also exalted angle does not work with the amnazing card pulse of the fields which destroys goblins even more so than angle. pulse is also faster that exalted angel. panotic mirror should be an obvious choice becuse you can imrint almost any card in your deck onto it. i am not shure if i should play 1 more panoptic mirror. please give me suggestions. i also know my sideboard needs work.
