It is quite powerful. It has the same feel as Brann Bronzebeard or Fandral Staghelm that they all need to be killed ASAP. It is a strong support for aggressive decks who have been battered with all the Priest love and healing this expansion gets.

Wait what if you try to draw a card but have no more card in your deck? Does it still try to draw?

They should have named the card White Eyes with token Blue Dragon >.>

I think you are missing the main worry of this argument? If you are not playing this card then this card is equal to a dead card in your hand, like a Sylvanas Windrunner or Mind Control you can't use. In the end, you often HAVE to play the summon option against midrange or aggro decks because you are deprived of getting ONE more useful card that you could have instead have, namely Swipe, Innervate, Wrath.

And again as I have said, 1 mana 4/4 is great, but with so many Druid card revealed already I don't think there will be more addition to the Druid's Jades to make the Jade helpful in the early stages of the game. Compare it to the 4 mana 4 damage and 2 mana 2 damage Jade cards Shaman and Rogue respectively are getting, they are easily better midrange options for Jade decks.

There is a contention of whether Jade Idol is good or insane. Breaking down the points:

1. It's not bad. 1 mana 2/2 of Enchanted Raven is in my experience "Playable", so 1 mana that has the possibility of growing into 3/3 or more is indeed insane. This argument is not without flaw, because even the smallest stat advantage matters in the early game and 1/1 for 1 probably loses you the game. Compared to other cards it does not pack a great punch against aggro decks. It is still a 1 mana spell though, and cheap spells are great against aggro. So it's a pass.
2. It denies fatigue damage. This is big. On the condition that you have one Jade Idol in your endgame, it will act as the endgame value to the level unprecedented by even Lord Jaraxxus, Elise Starseeker, Prince Malchezaar, Justicar Trueheart and Dreadsteed. In practice, Druids have additional chances of getting Jade Idol using Raven Idol and Lotus Agent (now that the Jade Golem mechanic had come out, I can see why this card is badly statted), so this is not hard to pull off. This news is bad for ONLY heavy control decks because on the chance the game gets into the endgame, they automatically loses. But only them. Jade Idol is hence auto-include in fatigue and control druids.
3. Jade Golem gets stronger for each Jade card in your deck, but there does not seem to be more Jade cards for Druid. So the card efficiency in the mid-game is rather bad, and Druid may lose facing against Midrange decks. Druid already lack tools against them (at best only Mulch or Naturalize, the latter does not see play), so against them Druids will lose against their Board pressure and loses the game within turns. With Yogg-Saron, Hope's End nerfed to be worse than Deathwing, Druid no longer has reliable clears to boardful of 5 and above minions. Even if 1 mana 4/4 is plenty strong argument to say the card is not weak in the tempo department, the 1/1 ,2/2 and 3/3 that comes before it is the reason I believe otherwise.
4. Unlike Raven Idol, this card does not work well with Arcane Giant, Yogg-Saron, Hope's End and Fandral Staghelm because it only represents ONE playable from hand spell.

What I believe, this card is surprisingly balanced with enough bad points to counteract its minus. What I am looking forward to see is the re-emergence of fatigue druid with efficient double Naturalize and double Coldlight Oracle (Coldlight is amazing! It draws you more tool to combat the board while allowing Jade Idol's value to grow quickly)

P.S. Even if balanced, I still voted the card meta-defining because the way control decks operate will forever be changed in Wild

its effect is not good enough to make an opponent think twice about clearing your board or bursting your face down with spells.

When you're trading, that is.

From 6 mana 2/3 to 6 mana 1/1... I feel sorry for druids. Maybe awesome if transformed instead?

This is a nerf I cannot agree. Everyone noticed that Hex is a very powerful Shaman card from HS' beginning, but it was not a complain because it was an upside to a terrible hero power, much like how Execute in warriors is an upside to a hero power that does nothing to the board.

Hex's mana cost is interesting from a design standpoint because 3 cost spells is a sweet spot, and works really well with the intended epic Far Sight and LOE's Jeweled Scarab.

And shaman gameplay relies on having massive single-turn board swings, so having a 4 mana cost Hex does not tally with this principle. On top of that, Hex trades a card for an enemy minion, which is one or less of opponent's card. This concurs with the general observation that Shaman used to have poor card economy (lack of draw options, spells dealing limited amounts of damage).

While it is strong, it's not the card to see a potential nerf, not as much as the blatantly powerful Maelstrom Portal. Still, midrange shaman is not the worst deck to rule the meta.
