Sideboard

Deck focuses around Death Pits of Rath and Caltrops.  Basically gives you control over their attack.  Basically they die before they can actually do damage (providing they aren't indestructible)

Use Vampiric Tutor to get the combo up.  Stuffy doll is for Shivan meteor and Player pokes...may remove that in exchange for something better.

Panoptic Mirror is ideal for Demonic tutor, but pretty much any of the instant/sorceries can be imprinted.

Everlasting Torment and/or Meekstone (sideboard) would be used for indestructible that can punch through Pits/Caltrops
