Unholy dk to give presence.
Glyph for healing touch.
Maybe not enought to keep tank up alive but definately good pair with sheat of light paladin to keep tank up and running. You keep hots running and spam healing touch while getting extra 1% cheaper casts for sheat of light as well.
flourish, reju, 3x lifebloom and sheat of light for 6% cheaper healing touch and then just spam away.
