This card is OP not just because of its stats and its effect but because of Dragon tag. It triggers "dragon-holding" minions and it can be discovered by Netherspite Historian. 

I think only Druids can summon this guy thanks to Jade Idol.

Without considering Brann Bronzebeard and discovers (Lotus Agents, Finders Keepers, Journey Below etc.), Shaman can summon up to 10/10 and Rogue can summon up to 8/8. 

Blizzard said that there will be no addition to Standart Format for the removed 6 cards. 

However, what will be your choices for the cards that removed?

• Ice Lance -> Duplicate (Pretty nice combos with this card)
• Power Overwhelming -> Voidcaller (This can make Demonlock viable)
• Conceal -> Tinker's Sharpsword Oil (Balanced and perfect card for Rogue)
• Azure Drake -> Antique Healbot (This card is necessary to stop aggro meta)
• Ragnaros the Firelord -> Kel'Thuzad (Unique, strong, hard to play)
• Sylvanas Windrunner -> Justicar Trueheart (Its is not staple, good in control decks)

Here's mine.

This card was the one who holds aggro decks. After Standart format, aggro ruled the meta for a year. Hope to see a card like this in next expansions.

Instead of nerfing this OP card, you're giving it "Elemental" tag !!! GOOD JOB BLIZZ !!!

Discovered it from Dark Peddler to kill poor Murloc Warleader.

Nobody mentioned about the beloved Dragons.

Goodbye Dragons, goodbye Alexstrasza's Champion, Blackwing Corruptor and others.

and goodbye Elise Starseeker, making control decks great.

F*ck, Darkspeaker swapped the answer. You're doing it wrong mate!

The problem of this card is its supporters. They are just vanilla minions which can't do anything unless you play this. If Blizz had created more interactive cards, it would have been playable. 

In Wild, yes you're right. Because the pool of "really good" cards for each classes are growing in every expansion/adventure (more AoEs, more destroy effects, more Taunts, more Deathrattles etc.) and it's not hard to create a 30-different card decks. I don't know, after 2-3 expansions, every classes in Wild could run Reno Jackson and N'Zoth, the Corruptor along with other staples Dr. Boom, Azure Drake, Sludge Belcher etc.

However in Standart format, we have limited amount of card pool, thus limited amount of "really good" card. There would be other "no duplicate" cards and warlock got really bad legendary card in MSoG. I don't think, we will see Reno.. pardon.. No-Duplicate Mage or No-Duplicate Warlock in Mammoth Year (May be we should rename Kabal Mage or Kabalock). But I'm sure we would see Kabal Priest thanks to Raza the Chained.

• Warlock - Quest: Discard 5 cards / Summon 7 Demons. Reward: A "demon" which shuffles discarded cards back into your deck.
• Druid - Quest: Summon 7 Taunt / Adapt 7 times. Reward: A minion which sets your Mana Crystals to 12 or 15. 
• Mage - Quest: Cast 6 Spell / Play 3 Secrets. Reward: An "elemental" which reduce the costs of all spells in your deck; or shuffle copy of every spell you'cast; or an unique effect which related to spells.
• Rogue - Quest: Play 6 0-Cost cards / Play 3 non-Rogue class cards. Reward: A minion which have Stealth and really powerful combo (may be related with non-Rogue class cards)
• Paladin - Quest: Summon 5 1/1 minion / Give +1/+1 to minions in your hand by 4 times. Reward: A minion with Divine Shield and gains +3/+3 for each minion you've got. (Probably useless garbage)
• Shaman - Quest: Summon 7 Elementals / Overloads 14 times. Reward: An "elemental" which deals damage to enemy hero equal to your total Overload this game. (Shaman meta continues...)
• Hunter - Quest: Summon 7 Beasts. Reward: Another "beast".
• Warrior - Quest: Lose 18 Health / Gain 18 Armor. Reward: A "minion" which switches your Hero Power with another weapon slot.

Like Deadly Fork and Sharp Fork.

Quest is great mechanic but I have so many things that I wonder :D

1. Quest cards count as a spell ? (for Spellslinger, Gadgetzan Auctioneer etc.)
2. Can you have more than one quest at the same time ? (can be gained by Thoughtsteal, Burgle etc.)
3. Does this card consume Legendary slot for class ? (Will Priest gain a Legendary minion or Mage gain a Quest ?)
4. What it will look like used together with Secrets in your hero portrait ?
5. Reward is going to your hand or your deck ?
6. Will there be a way to interrupt or destroy enemy Quests ? or shortly any Counter ?

Really cool mechanic.

But, Adapt choices are not balanced, I think. Taunt is not equal to Divine Shield or Windfury.

I think, other choices could be: +3 Health, Stealth, Spell Damage +1, Deathrattle: Draw a card ?

You've kept saying "I have no time for games.", but I never thought you would go from this game. Now, you will have so much time in Wild...
