Thats something i miss in a Discard-Lock, controlling the discard to make stuff like Fist of Jaraxxus better.

Also you dont have a big drawback adding 2 of these to your Deck, because you can just choose to discard the other Control the Void instead of any other Card in your Hand.
Maybe even draw a Card with Malchezaar's Imp

A turn two play for priest that completely changes their playstyle. By removing the Hero Power and drawing faster, it makes Priest weaker in Control game, but opens up possibility for Aggro Priest. Playing two of these will make you draw 3 cards at start of your turn, which is a weakness in itself since you're going fatigue and mill so much easier.

This is my idea for this week, hope you like it.

With this card I introduce a new mechanic in HS, the Curse (negative effects) and the Blessing (positive effects), spells with a permanent effect trough the game.

Considering that I am allowed only one submission I only made a curse card, but maybe in future Card Competition I ll have the chance to make a Blessing.

A little bit about the card:

If you choose one of them, you can choose the same one later (in which case the opponent will take 2 damage at the beggining or end of the turn) or the other one (in which case the opponent takes 1 damage at the beggining and 1 damage at the end of the turn - if he doesn't have exactly 5 cards in hand.)

Good againts aggro decks, good againts control decks, perfect for Mill Druid.

Maybe the real dragons were the friends we made along the way.

Hand full of Dragon Synergy cards but no dragons in hand to activate them? After casting this card, so long as you have at least two minions in hand, you're always good to go. Naturally, this card's primary effect becomes less and less relevant as the game goes on, especially if you already cast it once, hence the cycle effect; a potential gimmick for Priest going forward would be adding a 1 card cycle to otherwise incredibly niche effects, as Power Word: Shield and Mass Dispel demonstrate. If you put two of these cards into your deck (or, say, draw it with Chromaggus), the second casting becomes a cheaper Arcane Intellect, with the understanding that it's one less otherwise important Dragon Priest card you'll be fitting in.

In the late game, playing this with Chromaggus already on board as a tech choice makes it a 2 mana Sprint, in a way. And the combo potential with Deathwing, Dragonlord goes without saying (granted, there'd have to be some cards where you wouldn't mind being instantly pulled out without Battlecry, like Priest of the Feast or Sylvanas Windrunnner)

My entry, manaripe is a combination of wild growth and mistcaller giving druid better tempo or bigger minions [the reduced cost may be better but druid can use this to set up combos] this can be used to get out living roots and trents to then use savage roar, etc:

Benevolent Decree

The Divine Shield on the battlefield divide must be damaged first with an attack/hp/spell. Hinders the use of the Hero Power for aggro, but might aid the control opponent. 

INFINITE MAGMA RAGERS

This only applies to actually changing the set amount, so simply dealing damage to a minion won't work. However, hitting someone with a razed alchemist will.
