Down at my college we have a weekly vintage tournament (no proxies). Normally I ran Ichorid, but that has been hated out of existance for now. I decided to try and build a storm deck. This is the decklist I have so far:

Deck (60)
   
Creatures (1)
  1 Inkwell Leviathan

Spells (35)
  1 Mystical Tutor
  1 Vampiric Tutor
  1 Merchant Scroll
  3 Ad Nauseam
  1 Gifts Ungiven
  1 Brainstorm
  4 Dark Ritual
  1 Demonic Tutor
  1 Repeal
  1 Necropotence
  3 Cabal Therapy
  4 Duress
  1 Demonic Consultation
  1 Ponder
  1 Mind's Desire
  2 Tendrils of Agony
  1 Chain of Vapor
  4 Cabal Ritual
  1 Yawgmoth's Bargain
  1 Tinker
  1 Yawgmoth's Will

Artifacts (9)
  1 Mana Vault 
  2 Sensei's Divining Top
  1 Engineered Explosives
  1 Mana Crypt
  1 Pithing Needle
  1 Chrome Mox
  1 Sol Ring
  1 Lotus Petal
 
Lands (15)
  2 Flooded Strand
  3 Polluted Delta
  1 Watery Grave
  4 Island
  4 Swamp
  1 Tolarian Academy

My main question is should I be running Force of Will, and if so what should I cut? The metagame is mostly aggro decks and some control decks (mostly counterspell based) and one Earthcraft deck. Any other tweaks and suggestions are also welcomed.
