Remember that you are an aggro deck. As such, you want to lower your mana curve. You don't want to give up on card advantage, but you are willing to ignore life gain and pay some life instead.

• Bone Splinters. March of Wretched Sorrow These are card disadvantage. Try Dismember and Fatal Push. Notice that it mentions "permanent left the battlefield". This works well with your ninjutsu.
• Soul Transfer. You have no chance to control both an artifact and enchantment. If you want to destroy planeswalkers, go with Hero's Downfall.
• Assimilate Essence and Scatter Ray. Playing counterspells that hit just creatures is bad if you are playing black. Either play an universal counterspell such as Mana Leak, or play direct removal which can hit creatures that are already on the battlefield.
• Battle-Rage Blessing and Return to Action. Search for a 1 mana alternative with an unside, such as Feign Death, Undying Evil or Slip Out the Back
• Collective Nightmare, Anoint with Affliction and You Are Already Dead. These are garbage. Play any of the good 2 mana black instant removals, such as Cast Down, Doom Blade, Go for the Throat, Infernal Grasp, Ultimate Price, Power Word Kill, Heartless Act
• Ertai's Scorn, Extinguish the Light, Debt to the Kami. These are somewhat a little too expensive. You are an aggro deck, so play more tempo oriented cards. Try something from Remand, Memory Lapse, Undermine, Clawing Torment.
