U/B Delver Help

i have a deck like this, i would say take out the spellskite, the dagger, the disperse, the victim of night, 2 dissipate, and think twice. put in snapcaster or augur of bolas if your on a budget. runechanter's pike is great with this kind of deck so i would have it replace the daggers. add like 2 or 3 forbidden alchemy to search for either the pike or answers while putting instants and sorceries in your graveyard. put in your choice between 2 go for the throat or 2 doom blade. like 2 or 3 thought scour and i would suggest to thought scour your opponent until you get a pike. 2 or 3 gitaxian probe and when you cast it write down whats in your opponent's hand. vampire nighthawk and bloodline keeper are great in this deck, you can decide how many to run of each. gut shots are one of the most amazing cards in delver, because everyone runs creatures with one toughness and if not have it kill something after combat. i would also run a phantasmal image main board in case of an aggresive match up, its a good main phase snapcaster or augur of they don't have anything. i would sideboard 2 torpor orbs for flicker decks and mirror matches, if you do this side out some but not all of your snapcasters or augurs. put the 2 dissipate in your sideboard against thinks that ramp out of range of mana leak. 2 steel sabotage for sword and artifact decks. well thats a good start think along those line and it will be pretty legite :)
