Quest Warlock. Play this card. Play Plot Twist. Legendary! Zoolock. Play this card. Play Plot Twist. Legendary!

You can also play it in a Rogue Galakrond deck for the memes.

Also, it's crazy in Arena but I think …

Fun meme card that you'll play if there are Bomb Warriors or decks with Hakkar. Apart from that ... not good.

In wild it could work when you play against DK. You play this card and then you play Sir Finley Mrrgglton. No more Frost Lich Jaina or Bloodreaver Gul'dan hero powers

Only increasing the cost of the hero power 1 mana it's not good enough. I don't think any deck will run this card. It's OK for Arena

Excellent card! Great for pirate Warrior and Rogue Decks with Spectral Cutlass.

At first sight it doesn't seem that it'll see any play. Maybe to dilute the resurrect pool for Priest. 

A 4 mana card that has 8/8 and rush if your opponent controls a Dragon? Bonkers!. Also a powerful card in arena.

Great neutral card. There's a lot of useful 1 mana spells in every class. The obvious choice being Mage. Being a Dragon it may find home in Dragon decks too.

Also pretty good in arena.

Powerful neutral card. I see it in Zoolock decks.

The only deck that can include this card is Taunt Warrior. It can also find a place in Paladin Duel decks or Big Shaman but I don't think it'll see a lot of play. If you get it from a …

Maybe it won't see any play in standard but in Arena the card is excellent.

Not a good card. At best it acts as a taunt to delay aggro decks. Maybe it could work in priest with Power of Word: Shield on the coin.

Great card that will find it's home in all Dragon decks. Good stats and excellent battle cry

A counter to highlander decks and a decent 3 cost minion. It also fills normal decks with useless 1/1 minions. I think it's a pretty good card but I don't know if it'll see a lot of play.

This it's too expensive. You want cheap mechs or that can magnetize. Maybe you play it to prepare some kind of combo.

Too expensive. Won't see play even in wild. Good for Arena.

Not sure if you add it to Dragon Decks but it's pretty great in arena. 

At last! The card that destroys the enemy armor! Excellent card in wild against Druid & Warrior. In standard it'll depend on the meta.

You play a 5/5 and draw a card. That's good. I think it'll see more play than we think.

An arena card. The random damage makes the card not good. Maybe Quest Shaman will play this but there are better battlecry options, though.
