Mono Blue Control

ive been tinkering around with this build for a while and ive come across a few small (read: large) issues. 1) manlands have to be dealt with yesterday. they are the biggest pain you will have to deal with aside from 2) vengevine bloodghast. because of those creatures, i was actually thinking of putting wall of frost in the sideboard since they do a decent job of holding the vengies off for at least a little while. when it draws its counters, its insanely hard to stop. frost titan, while being the worst in the cycle, is still quite a strong finisher. it forces your opponents to pay 6 for pulse, 5 for terminate, 4 for path, so it makes mana leak much stronger. i need any and all comments you might have. my sideboard is kinda meta-influenced, but any overall suggestions would be great! Against faster decks, side out the All is Dust and side in Narcs and Calcite Snappers (and more than likely Flashfreeze). Once they empty their hand, they are at a HUGE disadvantage, but with your constant card draw, you should be able to race them just fine.
