Brain bashing

Note: Deck created only with cards I physically own and are not part of other decks. The idea of this deck is not to necessarily flatline the runner via brain damage, but to make them too hesitant to run while you score out HB's abundant 3 advancements for 2 pointers. I don't think I'll actually trigger Accelerated Beta Test most of the time. Economy is weak, ice is weak. Might need some work there. Influence is all dumped into Marcus Batty and Valley Grid. Batty can sneak in a brain damage, and valley grid can flatline via -1 max hand size. Any advice on how to improve is appreciated.
