It's possible it'll see play, seeing as at worst this will do something like making a Northshire Cleric a 3/9 - which isn't a terrible statline - but it's such a shame that for only 2 mana more than Velen's Chosen, we only get 2 health and no spell damage.
Velen's Chosens big brother. The 5-mana slot has always been a weird place to fill so this might see some use there to curve out better? Nothing particularly new and exciting, but at least it isn't (yet another) gimmicky priest card.
Unfortunately, I can't see the +6 health being much better than the +4 health that velen's provides. Also no spell damage for turn 5 holy nova. Might see some play in decks with health buffs but man is it expensive.
