This deck is meant for direct idol damage. Invocation Sentry deals heavy damage to opponent idols, with the help of Sanctuary of the Lost and Omen of Damnation. Loyal Darklings can be sacrifised to deal 5-7 damage (With Hex Marks and Wicked Being.) Watcher helps with the damage by dealing idol damage after the Darklings are sacrifised, and Halls of Oum Lasa let the destroyed Watchers/Invocation Sentries live on. Rattle Hymn allows lingering card draw, and and Eager Scryer allows for consisitent damage and card draw.
