this card heals to full health the minion if minion is 7/7 remainin healt is 5 it will deal only 2 damage
This isn't true. Restoring a character to "full health" has always meant instant kills in Hearthstone, regardless of your existing Health. This can be seen through Reno Jackson and Tree of Life. Both those cards used with Auchenai Soulpriest, result in an instant death. They might have changed that with this card to keep it balanced, but most likely they did not as it is inconsistent with what's been released before.
Injured BlademasterHozen Healer Not too bad. Plus all the healing to damage effects. Might be in a strange deck. Not sure its value enough to be in a top priest deck, but I think it will definitely be fun.
