This seems really weak to me. Like priest has better options after rotation. I feel like this is here to make Sister Svalnas Vision of Darkness slightly worse. 

So, this does nothing when played but afterwards you can cheat a TON of mana. Well, 3 mana do nothing is honestly not that bad considering priest has so much removal and lifegain. And thanks to Sister Svalna you can discover a shadow spell each turn for only 1 mana. This will 100% See play in control priest decks.

Also this can be discovered, which means shadow priest decks can still get acces to it. Also reminder that this expansion will have a low card pool, so discovering this will be pretty easy. (Thank yogg that multiple Love Everlastings don't stack.)

In wild. Oh boy am i "happy" to see a turn 3 Love Everlasting into turn 4 Shadow Essence. This will be so much "fun"... And i bet that if BIG Priest gets too good thanks to this card, they will just ban it instead of deleting Big Priest...

Eh, alright. It's some nice value generation and removal in one. My guess is that this mostly will see play when it's generated by Love Everlasting + Vision of Darkness.

This feels nuts. You have a bunch of ways to heal this a lot, and this can easely summon a bunch of minions. Also this basically has taunt, because your opponent will always kill this ASAP. This will see play in some kind of heal priest deck, but i feel like it's good enough to see play in a few other priest decks.

Both versions are really good for control decks, this will 100% see play in control priest decks.

Not sure about this card. It seems like a really nice finisher in a heal-focussed priest deck. Slam this down, and heal a ton for lots of damage. Not sure how good that will be though.

4 mana sprint that tutors is insane. 5/5 star card, this will see play for a long time.

Good in Big spell mages, especially for more Pyroblasts alongside DJ Manastorm. 

In mech mage you might just include it to get more Seafloor Gateways.

Seems alright to me.

Random elemental support. I guess this forshadows elemental shaman in a future set? (I HOPE) Seems meh in standard/wild. In arena it might be nice though.

Seems like a good combo card. Repeat this a bunch, get more with Rewind and Infinitize the Maxitude (Only this expansion, cuz of the small spell pool.) Also you can use Grand Magister Rommath as a finisher if you recast/discovered a bunch of Lightshows. 

Very good with Shooting Star and Spectral Trainee. Sounds strong, but it might be a bit slow. And i'm not sure if this card is what mage needs.

Seems better than you might think. Seems good for burst decks. And it's a 4 mana 4/8 and +2 spell damage. That's pretty good stats, and the effect is not that bad to trigger. Seems good to me.

Pretty good card. Helps mage fight for board, while also rewarding you for playing spells. This seems pretty decent.

Such a good card, will simply see play in a LOT of mage decks for quite some time. After all, spells you play are probably pretty good ones AND because you discover them you also recast them with Grand Magister Rommath. 

Seems bad considering you have to discover last, however this does refill your hand a lot alongside Grand Magister Rommath, and of course helps you recast a bunch of spells you discovered. 

I feel like this will certainly see play during festival of legends, because of the small spell pool. But it will probably fall off once more sets release.

DJ Manastorm, and next turn 2x Pyroblast + 2 Fireball or Firelands Portal For 30-32 damage. It's quite slow, but i feel like this is a good finisher for some mage decks. But hey, at least OTK mage is back i guess? 

Banana's, but they dont clog up your hand? This seems pretty good. Especially with Jungle Jammer or simply to get a few more buffs. Worst case scenario it's 3 mana give a minion +3/+3. Not that bad.

Good one drop, and these buffs are nice. Seems good to me.

MONKE. Okay this seems really good actually. This works well with midrange hunter decks like Beast hunter, as this doesn't mess with the ress pool and the summon from deck cards. 

Rating this a MONKE/5 stars. Glad to see Silverback Patriarch return to standard.. in a playable form. 

This simply looks bad to me. Just 1 damage? Meh. Compare this to Deathchiller. Sure Arrow Smith targets lowest health enemy, but i feel like you prefer more damage over that.
