4 Legendaries Dragon Handlock

Hi everyone.  I know there are many versions of this deck....and like most I'm still trying to figure out the one I like best.  Here's the list I'm running now...climbing from rank 8.

The deck is Handlock.  The idea is to mulligan for Mountain Giants and Twilight Drakes.  Tap your first couple of turns and play a cheap Mountain Giant or a big Twilight Drake.  You can make big taunts easily with Abyssal Summoner and Sunfury Protector.  Then you can play Alexstrasza to drop your opponent to 15 health.  Then finish him off with Leeroy Jenkins, Nether Breath, and Soulfire.  Even Scalerider can deliver that last few damage you need.  This deck has a lot more reach than it seems, even without Malygos.

Cards I left out:

I don't think Malygos, Valdris Felgorge, Evasive Drakonid, Frizz Kindleroost, or Zzeraku the Warped are needed.  You can certainly try one or two...I'm just leaving them out for now -- mainly because they cost a lot of mana.  This also makes the deck a lot cheaper, and I think it's still pretty good if not better w/o most of these cards.

Cards I would consider replacing:

I just added the Sea Giants...not sure how good they are.  Soulfire could be cut too.  You could maybe cut Faceless Rager, but I've gotten great value from that card.  Alexstrasza isn't necessary either.

Other Cards to Consider:

Firetree Witchdoctor, Mortal Coil, Bad Luck Albatross, Shadowflame, Lord Godfrey, Dragonmaw Poacher, Siphon Soul

Let me know if you have any ideas.  I'll keep trying and post an update if I do well.
