Heh. This card. For a cost of 3, and the discipline talent requirement- you can make an ally almost indestructible. It can still be removed from the game- because the card would be put into the removed from game zone- but if you try to deal fatal damage to an ally or pop a cap into him, he won't go away because of Soul Warding. If you are running a big bomb ally or a friendly player is- Make this more of a pain in the ass for the boss player by playing this card- even for automated decks. If you combo this card with Saurfang the Younger, who re-readies after entering combat with an ally... oh dear god. Can you say ally board wipe for the boss?
