Someone on reddit did a list on what legendaries are good to pull with this and it's honestly a pretty large amount. There are only a couple really bad ones and more highrolls than bad or moderate rolls. I'm not sure there is an exact deck it will go into but the card itself seems pretty good and may not see play simply due to it not fitting into current shaman decks.

Well stated card but it all comes down to priest having a deck that this can fit in. Stuff like rez preist can't afford to run it and I don't think inner fire is really looking at this and wanting it. Seems like it's just gonna go in any deck that [Hearthstone Card (madam lazul) Not Found] would go into which currently doesn't really exist but the chance of something like galakrond control priest coming around could be the home of it.

We obviously will need to see what dragons paladin has access to but it seems interesting in that you can possibly curve Cathedral Gargoyle into this to hopefully make sure you get that value going without falling awfully behind on board. Making massive dragons while playing on curve is very powerful so we'll see how this does. Silence could be an issue but that's gonna be entirely based on the meta.
