Welp, time for Mecha'thun memes

I would argue meta-defining only because its perfect for meme suicide decks. Can work alongside Unlicensed Apothecary for 2 win conditions in warlock!

"Keening" is a word?  

Keen - verb

Wailing in grief for a dead person.

I say one of the reasons this card exists is for RNG shenanigans like (d)evolve, random summons and stuff, sothat we can get the occasional combodeck ragequit youtube video.

Remember, some cards don't need to see play, they just need to exist.

I rate this card Playable

Removing cards from your deck isn't a drawback, unless you are running a deck with synergies and combos.  Just like how a deck with 20 cards isn't inherently worse than one with 30 cards.  

If you play aggressively you won't be milled either.  The game will end long before you Fatigue.

But anyways, the stats are good but not great, and you need great cards in Constructed.  So it's Playable in my opinion.   

exactly

this is playable in jade druid 
after you have your combo Gadgetzan Auctioneer + Jade Idol your main goal is to mill the rest of you deck asap, to get insane value from it

this is turn 10 or 12

That's smart of you, I had not considered that.  

Mill your deck, shuffle Jade Idol, and pump out Jade Golems

Clearly this card is more than free dust in the right decks.  

[cardSkulking Geist[/card] will destroy your strategy.

Skulking Geist isn't that common currently 
and even if your opponent have it, there is a 50% chance that he'll draw it until turn 15, and you, most likely, already have a table of huge Jade Golems by that time,

so if 30% of players have it, and 50% of them play it, this means that you probability of loosing because of it only 15% 
of course there are other reasons to loose, and i'm not saying that this deck has a 80%+ winrate

but it is playable, and it is possible to climb with it !!!!!!!!!!!!1111one one

it is a fan to see how your opponent decides to leave Keening Banshee on table, and next turn you burn 15 cards, i bet opponent think you are on drugs or something, but you don't )

 ''unless you are running a deck with synergies and combos''

you mean the 95 % of the decks that are in the game ?

What an ugly face, I open 49 packs and already 10 copies of this wretched woman face.

Fel Reaver is back..... and even worse

as a 6/6 this would be fine.

This is similar to Fel Reaver but with 3 less hp and attack. Back when Fel Reaver was around you'd put it in an aggressive deck that doesn't care about losing cards. Keening Banshee would be played the same way, having you controlling how many cards you remove from your deck is irrelevant. It is on the edge of playable but no way close as how good Fel Reaver was.

The 4 mana RNG spot is really bad in this expansion.

Edit: I guess it is relevant to have you control how many cards you remove from your deck. You could follow this with one 5-drop next turn.

Still waiting for someone to post this Magic: the Gathering reference:

It would be a more interesting card if it worked like this.  

Maybe if it was an 4 mana 7/7

perhaps this could be used in a jade druid to quickly go through your deck once you have the remaining jade idol and an auctioneer.

This is vanilla stats with awful effect no? Why would anyone ever play this?
