It comes in at only two mana but can become a copy of any creature you own, assuming you exile it, so while they are only two mana, you generally want to wait to cast them until you have something big in play, like Massacre Wurm or Crabomination
War Room is a great addition to any mono-color (or colorless) Commander deck, since it allows you to pay three mana and one life to draw a card , plus it produces colorless mana without coming into play tapped
Your biggest rival will be Cogsworth, Grandfather Clock from Rise of the Floodborn, as his ability to give all other opposing characters +1 Resist will completely turn off your Sheriff as his reduced damage wont get through the Resist and Cogsworths Ward ability means you cant target him either
