Build a beast this with Swamp Leech and you’ve got no downside!

Lovely list.
I had gone to find this info and seeing someone else go through the effort to type it all out warms my heart. 
Something that made me laugh was looking at the cards other classes could get, if they got this card some how (Rogue and Priest spring to mind). Some notables include Zerek, Master Cloner and Cursed Castaway

7 mana 7/5, rush, taunt, divine shield... 
I like the way you think

So. Damn. Cute

Cenarious jr

Was gonna remark about the power of magnetic with stealth but...

steatherwock, that’ll be funny

Dr. Boom jr

Worse Mirror Entity... too bad

So Warlock is gonna buff this, play it for 2 copies, then zoo the control to death.

Nice

This lets Spirit Bombs negative be positive!

Quote from Dragonsscars >>

The funny things is that Team 5 is creating cards with Treant sinergies but will not create a Treant tribe.

 That would be sort of like creating the 'silver hand recruit' tribe.  Treants are a type of token that druid creates.  At least for the moment, blizzard doesn't seem to be intending to make any non-token card that is a treant.

 Priest was weak so Blizzard decided to give him a hand... or more

Okay let's say you play Dr. Morrigan, in the same turn you use Baleful Banker on it.

Next turn you play Spiritsinger Umbra and kill the Dr. Morrigan.

For some reason you have no other minions in you deck left.

Will there be an infinite loop until the structure of space and time shatters??

This expansion makes me craft older cards to achieve more enjoyment. There are too much funny stuff and posibilities here. I guess first time of my hearthstone life i will buy a pre-order.

Great, another way for Druid to get extra copies of OP spells.

How am I supposed to deal with 4 Webweaves?!

Imagine this card with Shudderwock, 16/6 that clones itself, seems legit.

This actually synergizes VERY well with the Sudden Betrayal, as this punishes attacks from small minions and hero power pings, while sudden betrayal can be dealt with by using your tiny minion to attack first, leaving the path open to large minions. If your opponent guesses wrong, they could end up wasting a significant attack.  

Ex: Your opponent has a Deathwing and a Murloc Tinyfin while you have a secret. If they attack with the tinyfin and it is sudden betrayal, they just lose the murloc and smash you in the face with deathwing; however, if you are playing evasion, the tinyfin connects and they lose 12 damage because you are immune. Conversely, if they attack with deathwing first, betrayal causes it to smash the tinyfin, wasting both attacks that turn. This creates a real choice that the opponent must risk, unlike with paladin, where all damage manipulation secrets favor the small minion attacking first.

Finally, this is REALLY obnoxious against bloodlust bursts.

I think that some people aren't being fair to this card. In most decks, it is trash, but Jaina can uniquely benefit from it by turning a small minion you draw in the endgame (Arcanologist) into a 6/6 threat, then using her hero power to turn this 1/1 into a water elemental. A 6/6 and a 3/6 for 7 and a trash minion isn't bad at all.

Alternately using this to eat a totem and then playing unstable evolution on the furbolg can create huge value and let you create a 10-mana minion alongside the 6/6 with only 10-mana. Also, the new shaman legendary can return this to your hand and make it cost 1-mana doubling the value.

Finally, a way to remove Ambush! and Burrowing Mine!
