Hearthpwn

basic card  like 

Ancestor's Call

Furnacefire Colossus

The key word is Mega-Windfury, as seen in V-07-TR-0N and Vorpal Dagger

Fenik can control his demons, but only for so long....

Something like this is tactical, a card to complicate timing and force people to plan around unusual options.

I designed this to have "Destroy your Hero" as the phrase from Lord Jaraxxus but as I did research I found that "Gain Stealth " is only present on three cards too: Lotus Assassin , One-eyed Cheat and Valeera the Hollow

"If that kills it" : Mortal Coil , Bane of Doom

Keyword = Banana.

Previously used on King Mukla and Mukla, Tyrant of the Vale .

Gotta show our Gorillas some love and revive some legendaries.

* Edit: Had an issue uploading the card

I think this qualifies.

Anyways, good luck to all of you!

EDIT: Forgot to put rarity into the card.

Her enemies can't see her coming, but if they did, they'd be blinded.

Uses the rare keyword Mega-Windfury which currently only exist on the two uncollectable cards, V-07-TR-0N and Vorpal Dagger .

Card uses the same words as Hooked Reaver

His mother-in-law cursed him twice.

"Double", like in Divine Spirit , Cursed Blade or Gahz'rilla .

Flavor: "What was I thinking?"

A high risk/high reward card: slim your opponent's deck and gives him a card, but can destroy his strategy by discarding a key card.

Rare wording is "Look at the top X cards".

Flavor: His friends call him 'Old Reliable', but never to his face.

Card for reference: Animated Armor

Card reference to Corpsetaker

Edit: Picture did'nt show up. Uploaded it in Tinypic.

Rare word: "If your deck has no minions"

Existing examples: Rhok'delar and To My Side!

Use of the Card: Well it would fit into the Hunter Deck without Minions. If you only have this minion in your deck (either 1 or 2) It wouldnt count as a minion, so all the "If your deck has no other minion" things would still work, even if both copies are still somewhere in the deck.

Muzea qualifies because dormant is only used on Sherazin and The Darkness.
The idea was to make a Hearthstone-equivalent of the (in)famous MtG-card 'Oblivion Ring'.

A take on Headcrack .

I feel like Repeatable this turn is a really cool mechanic and one card is not enough. Came up with an idea for Control Hunter which is quite simple but pretty powerful nonetheless.
