Hearthpwn

Next: anti-Murloc tech card (any card type, Hungry Crab as an example)

Next: a Rogue minion.

It's not hard to hide in plain sight when you're not the one the crowd is coming for.

(perhaps this requires further testing but i've heard 4 mana 7/7 are perfectly balanced cards)

Next: any card with singleton deck requirements (Reno Jackson, Kazakus etc.)

Next:

a Quest card.

Next:

Each turn means both your and your opponent's turn.

Next: a weapon.

Next in spoiler:

Forgive me for taking another bulbasaur art, this one just didn't fit the borders of  the card and i'm too lazy to stretch it up in an editor.

BULBASAUR used RAZOR LEAF. It's super inconsistent!

Next: Mean Streets of Gadgetzan themed card

So I might have had a whole demon hunter class set waiting in the wings for this one lol

Also did a new one with your art because it is amazing art. 

Next card. More Illidan's, create your dream Illidan everyone

Next: Let's go on with Illidan cards. Everybody loves Illidan, right? Feel free to use any Illidan art you like.

Since you didn't say what to do, take this one.

Next: a Hunter spell.

Next up: Show some love to Ser Brienne of Tarth

Flavor text: Nothing's more hateful than failing to to protect the one you love. No, and I don't mean THAT Lannister.

Next up: Now imagine a lifesteal warrior card for the image uploaded below.

 Flavor text: Lich King usually counted on a zombie clown to recruit spawns for him. If anyone seen that before, it is pure coincidential.

Next up: a powerful rogue weapon, but with such a big drawback tha makes it extremely risky to play.

Flavor text: Likes to bathe in the blood of his enemies

(Lifesteal triggers on all minions he damages)

Sorry we must have been making the card at the same time XD. How's this for a risky Rouge weapon, amazing stats, if your Edwin is alive and on the board.

Next. A Dranai Hero for Priest, find the best art you can for it.
