Exactly - at first glance i was like meh ... ok card but then i thought about the Discovers and yes - this one is pretty good

There are some good options to be discovered, including the primes. Good card

The pool is less narrow than you might think.

There are a lot of very bad neutral spell damage minions, enough that I don't expect this to see a lot of play.

Flexible, powerful, and more importantly, essentially free, since the minion you get will also get a 1 mana discount.

Good all around card that I just can't find reasons for mage to not include. For shaman it might be a little more trickier, but not by much.

It's a nice way to get spell damage for Spell-only Mage. Also Cyclone bait.

Mage : This can discover Astromancer Solarian and Ras Frostwhisper, so it will see A LOT of play in highlander mage, and mainly in burn mage, as they LOVE cheap spells. And they like spell damage minions as well so they can burst even more dmg to the opponents face. Also Primordial Studies can be discovered by cards like Magic Trick. So this will see a lot of use, even if you don't slot it in a deck. Also it will certainly see play in some Casino/Random Mage decks in WILD. (I certainly will. a chance to get multiple Astromancer Solarians is really good/fun!)

Shaman: This can certainly help out the spell-damage shaman archetype. This can discover Squallhunter and Ras Frostwhisper, so that's pretty good. Will certainly see play in spell-damage shaman, and maybe play in highlander shaman?

The bad thing about this card is the Discover Nerf from quite some time ago (Thanks Dr. Boom, Mad Genius and Omega Assembly), in this case it means that neutral spell-damage minions are as likely to show up as class spell-damage minions. This nerfs the card a bit, because there are a lot of bad spell-damage minions, like: Mana Reservoir, Dalaran Mage, Ancient Mage and Ogre Magi. (But of course this also means there is a chance to discover Bloodmage Thalnos as well = more card draw. Also there are not that many spell-damage minions in standard, so this downside isn't THAT bad.)

Right now the pool is great isn't it.. at just 1 mana i believe this can see play considering it benefits both mage and rogue

Primordial is just such a wonderful word.

It remains to be seen how useful this card will be. Although some Spell Damage support has come out with this expansion, most of the minions currently in the game aren't exactly stellar. If they continue to print good Spell Damage cards in future expansions though, this will definitely become a must have in those decks.

Woo-hoo, odd spell damage shaman let's go!

I gave this card 4 stars just because I really want Spell Damage to be a thing. 

I feel like a real Spell Damage deck is almost a possible thing in wild, it just needs a few more support cards. Hopefully this gives the deck a little bit more juice.

Cheap discover cards have always found a home in constructed, I believe this card is no exception.

Spell Mage and Spell Shaman have DESPERATELY needed some spell damage support for their archetypes, but more often than not slotting in a spell damage minion means having to remove a powerful spell from your deck you'd rather play.

For both classes this card can discover their class legendaries from AoO, Lady Vashj and Astromancer Solarian, as well as the spell damage minions that were introduced in RoS (although I believe that there will be MANY more spell damage minions introduced in this set). Discounting the minion by (1) makes it much more playable, as well, since what usually stops the spell damage minions from being played (aside from Malygos) is their cost and poor stats.

Other cards this spell synergies with is Mozaki, Master Duelist, Ras Frost whisper and Mana Cyclone to name a few.

This card can also be discovered by Magic Trick, Cobalt Spellkin, Wand Maker and Arcane Breath in standard, I'm not certain if Shaman can discover this spell in standard at this time. 

Regardless, a cheap, flexible card that gives a discounted minion that benefits Shaman and Mage's playstyle of using powerful spells to win the game. will see play

With the discover nerf too many bad spell damage minions going around.. sure you can get the good ones but not as often.. there's a reason those minions rarely see play, they are understated and normally too expensive.. the upside of this card is that it makes them cheaper at least..

Looks like they are making these study cards more interesting and useful than I thought they might. A way to get a discount draw on spell damage whenever you want seems very useful to me.

That card reduces the cost of your own Malygos to 8 mana. 7 mana if stacks.

Maybe that let malyshaman shine with the new innervate.

With 2x Primordial Studies and 2x Lightning Bloom you have 7 extra mana to burst the enemy with +5 spell dmg.

And Vashj Prime reduces the cost of spells... 

I don't know if It Will be good, but i'll try it for sure.

Around 55% for a good card for shaman, around 62% for something good for mage. (just counting non-basic not super expensive cards) 

Buff your spells by a minion you choose, and because of the discount the discover mana cost wasn't an investment?
Amazing, also as others mention, there not many spell power minions and in both classes ones that have it are the primes. This card seems pretty good.
