I'm unsure about this card. If priests get more impactful spells this could be really good. Being able to have upwards of 4 copies of a spell in a deck seems like it could be really really good. Pretty cool design but I'm not sure if it fits well in priest and I'm not sure how good it will ultimately end up being. I voted playable.
Not sure if this will be good enough for Constructed, but for Arena different story...Very good Arena card, allows you copy the most powerful spell option and one you believe you'll need or currently need.
Strong in a Reno Priest list, where'd you'd love to have 2 entombs/sw:d/dragonfire/etc.
And discover is great since the pool of cards is so small to choose from and you have complete control of what could come up. For example: add in a Greater Healing Potion, then discover it to have 2 against Pirate Warrior.
Won't see a ton of play, but has its uses for sure.
Very interesting card, can't come up with anything too crazy. With few spells in the deck you can basically guarantee what you get. Basically allows you to overcome the 2 cards per deck limit. Slow but flexible.
Only issue is that it will only work in wild with Thaurissan. Plus, we already pretty much had that in standard (Embrace the Shadows + Flash Heal + 2 Mind Blasts) and nobody used it. I guess it's one more tick of Thaurissan but still any reliance on Thaurissan for more than one card tick can be painful.
I'm hoping for some sort of aggro priest shenanigans but many of the best tools (Shadowbomber, inspire guy) are in wild. Still might be doable though depending on what we get. Two of these discovering two more Mind Blasts means good pressure to your opponent's face.
This is the closest to a tutor we will ever get in Hearthstone, and that alone makes this card good. If it were in a class with huge impactful spells such as mage it would be op, but since it's priest, with the cards we've seen for now, it's OK.
But remember; the power of this card is not to have a third copy of any spell you want, but to be able to fetch the spell you need faster. This is far superior than draw a card.
