Hearthpwn

Using this deck i got absolutely owned very quickly by back to back warlock Murlock decks.I even got  owned versus paladin as well and a Priest both those decks using buffs to easily vault over my early players.

I also got owned by decks using lots of cover with constant Taunt cards.I found nothing stays on board to make any use of the Sunfury or Argus too many easy kill cards in opposing decks.I managed to get some lucky draws and did get early damage and whittle opponent down to 8 or 9 fast but with not even power my opponents came roaring back.

Rank is very over rated as you can just have a 55% win deck to eventually move up after LOT'S of games.I actually had a losing record with this deck like about 6-9 and always felt like a struggle every game.

This deck is actually pretty weak,i think you were just lucky to get much results.I feel that of late there are a lot of very good decks otu there and i run into many that seem to get very lucky on the draw.

The problem with this deck is the card power is only a 1/3,meaning he can't kill anything and won't get past even a 1/2 or 0/2 taunt.

I have played the commander many times and won some games but his cost is too high,it gives you basically only one decent card to draw tha turn and by then your are facing probably some powerful cards.I found the commander was more of a trad eoff card ,not so often a winner with his 4 charge.

If i could give one answer to this deck is that it is VERY reliant on luck of draw,not the type of deck that should make rank 10 even.

PS:I have actually been playing a similar deck for quite some time,it is hard to get past rank 15.One of the major problems is that a lot of these cards need protection,the Sunfury offers none,Argus pumps these weak cards by one.Shields are weak now also as everyone has some sort of AOE dmg to remove shields.

This game as of right now seems to rely on three thigns and EVERYOEN si relying on that.

1 early speed

2 card drawing power

3 Luck and timing of the draw with Legendary cards.

Looks like a very interesting deck, I'll have to try it when I've crafted some of the epic cards. But indeed the rush decks might be a problem. Thanks for the deck and also, there is nothing wrong with your english.

I've been playing fairly similar for a while but made a few tweaks to mine after seeing yours. Gradually getting dust meant I could finally make the taunt rares which at times has been very nice indeed. 

I made a couple of alterations to yours, I got Sylvannas in a pack so it seemed a shame not to put her in for a yeti (i feel we have enough cards to cover a loss of a 4). Funnily enough one of the first epics I got was Pyro, shame I started playing after the nerf! However I dusted a couple of legens (Noz and Greenskin, shame they're a bit pants) and made Rag. I love him for the sheer panic he causes, and has a nice synergy with Faceless. 

It'll be interesting to see how I do as I go higher (or lower?) but so far I do love my mage decks!

I replaced 1 Acolyte out of 2 with Bloodmage Thalnos because it values with this deck :)

Thanks for sharing

Sorry for my english!

I reach rank 5 very easy with this deck.

The point of this deck is take early field advantage and to make your opponents take more steps (using more mana) to destroy your minions than he/she wants to. 
So always try to pick cards under 3 mana like Mana Wyrm / Argent Squire /Harvest Golem etc. You can make a nice combo with some spells and by using The Coin.

Against rushers, try to get a taunt creature out early. Freeze your opponents with Frostbolt to stop their weapons and take the advantage, destroy their early combo cards etc. The objective is to put a lot of threats on the field to do some damage to your opponent and make him/her attack your minions. Be wary of board wipes and don't overextend against hunters (who can play Unleash the Hounds).

I still try to do most damage to his hero to have ability to kill him with my spells in early and late game. You can abuse taunts etc. just take your opponent's hero to a small amount of health. With your minions, target only effective trades. Argent Commander is best for this. Use "fireball" on your opponent if you can, save your taunt minions and he has to take damage from that minion again (by using a weapon) or react with 2 plays.

This deck is weak when you don't get great hand at start (one of 4-5 games), vs some legendary cards (you need really rush them) and sometime vs warriors (mass shield) / healers.

It's also great and playable deck with lower cards - you can also swap out Faceless Manipulator for some Taunt cards at this mana cost and Pyroblast is a card great for rank 8+, it's not needed before.

[Edited this to be more correct english-wise. Feel free to copy what I wrote and edit your main post if you want. I would hate to see a bunch of misunderstandings spring up. Not a bad deck either. Good job.]

it's a nice deck but it's mediocre just like every other mage deck.  the reason why i say mediocre is because all mage decks are mediocre and depend on the draw.  A great deck should be flexible and have a fair chance of winning even on a bad draw.  the reason why you get to rank 5 with ease is because you're a great player!!  it's not the deck it's the player =P

Nice deck, had great success with.

I replaced pyro (don't have it) with a arcane explosion, it was useful against aggro or token decks.
