There is definitely a sequence of specific battlecries you'd want to repeat with bolner which could make a pretty insane OTK deck. Aside from that, dropping him on turn 2 isn't that bad, as seen with Efficient Octo-bot, and turn 3 would be a big tempo turn if playing a decent battlecry minion 

The first reward of unlocking overloaded mana crystals is huge, especially in conjunction with Lightning Bloom. This quest will definitely see a lot of play, but I don't know if a spell heavy shaman can actually be viable. The quest will still get better though after the release of more and more overload cards.

Super cool flavor and they still gave Rogue the sharks since Rastakhan's Rumble 😜 Pretty great deathrattle as those coins will be put to good use in rogue

Mini Spawn of Shadows, how cute. Will prob see experimentation in the new shadow priest I'm sure. Outside of that deck, it's not great

Cool flavorful meme card for Rogue, just like Yoink! is. Will be fun to play in the first couple weeks of the expansion but only if I get it in my packs

Arena or anti-aggro tech card. No control deck would reliably want to run this unless aggro is rampant in the meta, even then it's not great and only stalls for time. Maybe combo decks might use it

Team 5: "What theme do you want to give hunter this expansion?"

Answer: "Rats!"

This isn't a great card but it'll get your minions dying quite easily to trigger that dormant effect for The Rat King

Most times, you'll get a zero mana fel spell (seeing as there's 4 different 2-cost spells), it'll definitely see play in the new "fel spells DH" archetype, if it's any good.

Venomous Scorpid is 100 times better than this card, it's a complete joke. I guess you can run both if you want all that extra value

Those stats are so janky and the recruit effect belongs back in Dec 2017. No idea what blizzard wanted to do with this minion, but hey, least the deathrattle will trigger quite easily 

Certain classes like Rogue/Hunter could take advantage of this effect quite quickly. Could definitely seeing it getting added into Face Hunter

Very interesting design where you want a certain minion to take a lot of hits (plenty of frenzy minions for warrior) and some other good choices: https://outof.cards/hearthstone/cards/?hsclass=12&hsclass=10&text=takes+damage&collectible=yes&standard=yes 

kinda like a reverse Warmaul Challenger?

Sad to see him leave, but do wish him all the best in future endeavors.

A bit janky and in most cases, it'll only give you 1 card. Also doesn't really play to any game plan, so it's prob just your random arena pick or evolved result

Just your meme pack filler that adds extra random value. Might see play in Arena or from evolve effects

Decent tradeable SI7 card, should see a lot of play in a variety of decks, not just in quest Rogue

Maybe a combo deck would want to run this card? Super situation coz most times, the discover effect isn't actually needed.

I'm glad this card draw minion costs 6 mana. That means aggro can't abuse him as effectively as Voracious Reader. Definitely incentivizes more midrange, control and combo decks to be played. Will definitely see a fair amount of play and is probably the best legendary of the set, coz card draw is that good, until you get to fatigue

Warlock card in disguise? Other classes like Rogue or Priest could also take advantage of it as they can create some big hands, but I don't think those classes would really bother with this minion. Least it screws up the evolve pool in standard, even though 10 drops were bad anyway.

So it's support for deathrattle DH with the tradeable mechanic. Not that exciting, but least you can trade one way back into your deck if you have another on board. It might just not be enough to see play though
