Mad Demonic Sligh (v2.0)

this deck is a demonic sligh deck with madness thrown in as an extra kick. it does its job very well. just kills every creature your opponent tries to throw out. this is the build i'm currently planning on for regionals. any suggestions are welcome. mainly, how does the sideboard look? my local meta-game is mostly aggro so making a sideboard for a regional metta is a little tougher for me. i like the looks of it, the leylines get rid of the extirpate problem dredge fairly well. blood moon really slams some control decks while not really hurting me all that much. hit run helps me get rid of artifacts (due to the efficiency at which i can kill cretures,) sudden death is for dralnu decks black decks (replace dark withering.) and shadow of doubt is my one hope against dragonstorm.
