Yeah, it's a nice stealth sidegrade to Flash Heal. Much less useful with Auchenai Soulpriest and the like (can't burst down face, forces you to take damage to deal with the board). I honestly would play Flash Heal before it because of this, but I understand the case for this card.
It works well with Injured Blademaster, but that's the only redeeming factor. Losing the ability to combo with Auchenai in a good way makes it pretty bad. If you need to heal a minion you have your hero power anyway.
Honestly, anything you would do with this card you could use Circle of Healing for. Or if you need to heal face there's still Priest of the Feast. I guess it's important to have redundancy in face heals, but priest is still probably quite resilient without this and the other cards rotating out.
