This card can kill Lord Jaraxxus in one move for 0 Mana because Lord Jaraxxus counts as a Demon, and when your opponent replaces his hero with Lord Jaraxxus, his hero will count as a demon.
This card can be used in conjunction with Power Overwhelming when used on a demon. Since its effect is to kill the creature at the end of your turn, you can attack with the demon and after it has done some serious damage just use Sacrificial Pact on it to kill it first, and gain the health.
|Power Overwhelming||Common||Warlock||Spell||General||1||Give a friendly minion +4/+4 until the end of turn. Then, it dies. Horribly.|
In World of Warcraft Sacrificial Pact is a Warlock talent unlocked at level 45, where you sacrifice 25% of your demon's health to shield yourself for 200% of the sacrificed health, it lasts 10 seconds. If you have no demon it uses your own health.
