I just got in to modern on mtgo with a UW control build. Deck hasn't been performing as well as I had hoped and the sideboard has been a little disappointing. Anybody have ideas have ideas on how I could improve the deck? All suggestions are welcome! :)

I'd replace Condemn and Disenchant with two Oblivion Ring. This not only gives you greater versatility in being able to deal with things like Planeswalkers, but also in some cases such as against wormcoil, exiling is just better than destroying.

what decks do you usually play against? What sort of budget do you have for tweaking the deck?
