Eh, this card is probably clunky to use. You would want to use the damage effectively, but once you can trigger the deathrattle. You might end up throwing something out off curve when you can make use of the effect.

I honestly believe they will go to there original mana cost. The 1 mana cost is specifically from Academic Espionage. Augmented Elekk will most likely just be programmed with base copies rather than modified.

There is potential for it, but it seems obvious that with this theme that Blizz is doing with priest. They want them to play more tempo/deathrattle without question.

I honestly think this will still be too slow to be seen in meta. The four slot for mage is pretty competitive in what you will fit in and generally you won't be playing this minion for the stats, but for the spell damage. So it is not really a 4 mana minion from my point of view and we already got a better card revealed for that purpose with Celestial Emissary.

It is 5 cost in order to act as the middle ground in comparison to Equality + Consecration which is 6 mana. Though that still leaves to question why you would run this card over Equality.

There are two downsides to this card, but the positives do outweigh the negatives. First downside is that the cards are random of opponent's class cards (not deck) which could have poor results such as Totemic Might. The second downside further exemplifies the first in that you are inflating your deck by 10 cards which means it could become more difficult to draw into a card you would usually need.

This is why you will more likely use this card in some manner that exploits the value rather than depend on RNGesus being on your side. The fact the cards cost one though essentially prevents it from being punishing to use.

Turns out there are a lot of possibilities being made with Myra's Unstable Element. This card added a whole new one which is faster than Pogo-Hopper, but the question becomes if you can get the value you need from Academic Espionage in combination with Tess Greymane with them being random. Keep in mind, it mentions opponent's "class" and not deck.

Me used to trade for deathrattle. But now me no need to trade for deathrattle. Fireworks Tech is SMOrc best friend. Even make mech friend hit face harder.

Can pull Righteous Protector, Tar Creeper, Stonehill Defender and other cards that we don't know if they are meta yet like Faithful Lumi. Paladin is one of the few if only classes that can get proper value out of this card draw specification.

The difference with this and Hand of Protection is that the Divine Shield is not visibly on the field. So this is a case where you can actually use Divine Shield defensively whereas Hand of Protection would be used offensively because the shield can not be pinged off as easily. If Druid and Rogue are prevalent in the meta though, then this card is far less useful.

Yet another buff to Stonehill Defender

A lot of arena concedes will be due to this for sure

Im sorry, but I'd rather play Scarlet Crusader....

has nobody considered how powerful these 2/2 tokens are outside of combo? They're extremely valuable soft taunts which force your opponent to deal with them. In the late game that means a mage needs to choose between Frostbolting one of them or dropping Alexstraza

Being able to reroll your worst evolve with one more evolve tick is huge in evolve shaman many time evolve/devolve can cause you to lose with rng  (think nat pagle doomsayer lorewalker etc.) The fact that you can drop this on a mediocre board whenever and turn your hero power (which gets way worse late game) Into a full heal is crazy, the hero power is gonna be the craziest part of this card but trust me everyone would have already played a card that read 5 evolve twice.

Learned their lesson from Flamecannon, it seems.

I think the obvious comparison is Confessor Paletress, which is essentially a 9 drop for a 5/4, 2 healing, and a random legendary.

For this, you need some sort of activator that costs x, and this card is a 8 mana 4/6. This importantly takes it out of range of a lot of AOE's but makes it still weak to transformation or fireball. This reasonably means that pending the meta on transformation-type cards, you'll get 0-2 legendaries off this thing, and only reasonably more when you are already winning.

I just wanted to offer the opinion that the performance of this is clearly going to be very meta dependent. The effect is not immediate enough on its own, and its slow enough that being immediate is a huge deal.

Meta defining would imply, that next to all decks are running it, no? Or rather, that there will be an influx of new decks with tier 1 potential using this card.

In my honest opinion, this card is very good, especially for priest, but still falls short of being meta defining. You don't need a specific counter against it, and sometimes it won't even hurt to let it lay for a few turns (though that may be very dangerous, with all the health buffs and whatnot). I can see some Minion focused decks paying it, since it does scream value overall. 

In Arena, this thing will become bonkers, I reckon. Especially if you can protect it, and the enemy is out of removals.... I can imagine some scary dream-like plays with:
Northshire Cleric -> Shadow Ascendant -> Acolyte of Agony / Tar Creeper / Stonehill Defender. That can easily close a game, since nothing short of a boardwipe will get you enough tempo to return. All your minions you play will be understated (due to Shadow), and the healing of priest gives him even more control, as well as cards....

nah, he means that the effect itself costs 2 mana, so the remaining 3 mana gives you a 3/3 body.

I'm also surprised. People have complained for a long time that Priest doesn't really have viable 2-drops.

This is very viable and we're going to see a lot of her.
