Hearthpwn

I build this deck for a friend who just started playing Hearthstone. It seemed like we were doing pretty good with this deck. 

Here you will see some pure cards. 

Have fun!

Non-Basic Cards

• Mana Wyrm We have only one, you can use a second one if you do have it.
• Acolyte of Pain Best non-basic card in this deck, absolutely a must.
• Mirror Entity This card mostly earns you a turn while dealing a pretty nice amount of damage to your opponent. (Mostly unexpected in this meta.)
• Sorcerer's Apprentice A nice card, but not really important. Seems nice to play it to drop some aggression and you sometimes get great value if it lives.
• Firelands Portals are free from the latest adventure.
• Onyxia is the only legendary we have. So you can replace it with any high mana legendary to keep you up in late-game.

UPDATE:

Non-Basic Cards

• Mana Wyrm We were able to get the second mana wyrm.
• Acolyte of Pain Best non-basic card in this deck, absolutely a must.
• Mirror Entity I decided to switch one of these with an Azure Drake.
• Sorcerer's Apprentice Since I got the second one, I added both to create more board pressure. 
• Firelands Portals are free from the latest adventure.
• Onyxia is the only legendary we have. So you can replace it with any high mana legendary to keep you up in late-game.
• Azure Drake is a nice card to cycle and provides spell damage
• Cult Sorcerers have replaced Kobold Geomancer's.
