In order for this card to do any good, the meta needs to slow down a lot after rotation, which likely wont happen due to the quests remaining. There's really no point in this too for quest priest as you want to get the quest done and shard put in your deck asap, you don't have time to be fiddling around with drawing this thing. Will really only see play in maybe wild, along with duels as that's where you can play stuff like this.

Remember: This has already been tried with Waxadred which didn't see play and rogue has way better draw than priest.

This card will be OP In duels deathrattle priest deck

Slow, Slower, Priest.

I think Lightshower Elemental is just a better card 99% of the time.  That 1% would be when facing control.  If control makes a comeback someday this would be a very nice inclusion.  

I know people feel differently about these things, but I would prefer them to knock some stats down and give a card the appropriate tribe tag if there's an obvious tribe (like elemental in this case). 

It`s a Naaru, not an elemental.
