This deck got me from Rank 5 to legendary in 1 day (7/23).  It is totally broken, but it is going to be fixed with the week 2 naxx release.  So grab your free ranks now.

1) Card options:

Any card I dont list is pretty much required.

Mortal Coil 

Its a draw for 1 mana...whats not to like?

Haunted Creeper

the thing about this card is it is so sticky, and so you can get those DoA combos off so much easier.  this is one that you could dump for another standard 3/2 or 2/3 2 drop of your choice.

Dire Wolf Alpha

this is the bubble card to me.  Thats why I only have 1.  its pretty solid, and gives you another card to buff the egg, but the egg is so easy to pop that doesnt really matter.

Ironbeak Owl

counters other Zoo, silence that egg!

[b]Cards I dont have in the deck[/b]

Void Terror

you dont need more to pop your egg, and building around void terror is a cheese deck, which isnt even close to as good as this.

Elven Archer

This is the WORST card i see people regularly run.  It is straight up worse than mortal coil.  a draw is better than a 1/1.

Scarlet Crusader

sure fine, replace harvest golem with this.  I like golem better.

Blood Knight

The problem with this card is the only way you run it is if you are also running scarlet crusader instead of Harvest Golem, and at that point, I think you have too many 3 drops.

Faerie Dragon Amani Berserker

these cards are fine to replace haunted creeper with.  I think Dragon is much better than berserker though.

Argent Commander Leeroy Jenkins

the last thing this deck needs is more reach, I beat a handlock on like turn 17, you never run out of gas with this deck, the only way you lose is from getting behind, for example by having your hand filled with cards like this.

Leper Gnome

no.  this is a midrange deck not a burn deck.

Shieldbearer

only good in a combo, much better to just buff a 2/1 or whatever up than to rely on the 0/4.  also much easier to do without when you only have 1 dire wolf.

Young Priestess

so weak, bleh.

2) Matchups

I mean, honestly, its not that hard, the primary thing to remember is you are relying on battlecries that buff your minions.  dont let your board get cleared.  Also goes the other way when facing zoo.  IF you get ahead, always keep their board clear, and you will avoid a lot of comebacks.  I feel like there isnt a lot to say vs most other classes.  Vs Priest, make sure to buff your egg and kill it on the same turn, or it will get stolen from you.

3) Dumping

GOING FIRST: 

Basically, T1 is key. If you are going first, you need Voidwalker, Squire, or Flame imp in your hand T1 to make a strong play.  dump ANYTHING ELSE.  If you have one of those 3, then you can keep any 2 drops other than egg.  The only time you keep egg is if you have a dream draw, like flame imp, egg, and abusive sergeant.

GOING SECOND:

Going second is worse for you, but on the plus side, you have a lot more flexibility on dumping.  You can keep solid 2 drops, and you keep egg 90% of the time.  If you draw 2 other cards which are 2 mana or less, you can keep egg.  For example, if you draw Argent Squire, Knife Juggler, Nerubian Egg, and a 4th card, you can keep all 3, because if you draw something to pop your egg, you drop egg T2, but if you dont, you have knife juggler as a backup plan.  Also using the coin T1 isnt that great vs opposing zoo.  You are behind becuase you went second.  Its better to see where he is going with his drops before you use the coin to try to retake control.

Good luck!
