Here's what I would try: put in an engine that uses the graveyard and pit in a hand destruction or 2. It can be as simple as putting another dark or 2 and chaos sorceroro but not only would hand destruction help both silents, but it thins your deck and puts your cards where you want them. Other than that you need staples -_-.
-2/3 magician's circle (not needed, only 1 if you really want it)
-1 swords (not competitive)
-1/2 level up (too many)
-1 lightning vortex (never play more than 1, it will ruin your hand advantage)
+1 mirror force
+1 torrential tribute
+1 brain control
+call of the haunted
+2 book of moon
also try to cut it down to 40 cards
ALWAYS max out your extra deck. You never know what you'll brain control for
