Hearthpwn

Standart Mill Rogue (One of the hardest deck in Hearthstone and one of the most cheerful too)

How to play:

1) Fatigue. Draw all cards of opponent and win 
2) We burn lot of good opponent cards

Mulligan.

We need Coldlight Oracle.

Doomsayer, Backstab and Mistress of Mixtures are good in all matchups too.
You can keep Eviscerate or SI:7 Agent  if you have Backstab too.

Combos:

Bloodmage Thalnos + Fan of Knives - good combo to keep table free

Try to use Preparation  only for combo Coldlight Oracle + Preparation + Vanish

You can return your Coldlight Oracle with Preparation + Vanish on 6th turn. It is very useful if you lost the table. And often it starts burning cards of opponent

Matchups:

Good: control and Reno decks. Control Warrior, Control Priest, Reno Priest, Reno Mage, Reno Warlock (best), Miracle Rogue, N'zoth Paladin.

Middle: Dragon and midrange decks. Dragon Prist, Dragon Warrior, Dragon Paladin, Murlock Paladin, Control Jade Shaman.

Worst: all face, agro decks and jade druid (100% loose vs druid). Pirate Warrior, Agro Shaman, Midrange Shaman, Face Hunter, Secret Hunter, Midrange Hunter, Jade Druid. If you play for instance versus Pirate Warrior or Jade Druid - best decision is to concede. 

Changes:

Bloodmage Thalnos can be changed on Loot Hoarder 

The Curator can be changed on Azure Drake

Doomsayer  can be changed on Dirty Rat

All other cards are cheap to craft.

Overall:

In nowdays meta there are lot of Reno decks and there are more good matchups then bad, so this deck can normaly play in this meta. Use your brains and win ^_^

Good luck. Like please =)
