Strategy
Dealing 5 damage is straightforward, but since the buff is enormous and Demons generally have some backlash for playing them, losing it is often a double-whammy. 
Blood Imp is an excellent candidate; its low cost and Stealth allow you to keep its effect running until you need to use the Attack boost. The tanky Mistress of Pain will heal for huge amounts before going down. You can use it with Shadowflame for unexpected field wipes but this is very expensive and wastes the Health.
