The card that I made for Hearthstone is called the “Hellspawn Mage”.  He is a demon that has found a way to escape the trappings of hell to causes chaos in the world of the living. No longer alive he has imbued his sorcery with part of the energy that is “Death” in order to open a portal and rejoin of the world of the living.  This card is quite powerful due to the Hellspawn Mage being a general of Death’s Army.  

He deals 5 damage directly to your enemies health regardless of armor or any other protective armor or spells placed on enemy.  He also kills all the minions on the board except him, that is including all the minions on your side of the board as well.  Lastly at the end of the turn this card allow you to draw two more cards from your deck.  He has an attack of 10, his health is 8, and mana is 10.
