Ork hammer

Sure looks Orky fluff wise, but I felt that expensive Orks with equipments is not top tier in meta, as you need to keep valuable resources to drop your choppas and rokkit launchas, which you will find it difficult as the command hammers in this deck is kinda weak. 

A seasoned player will just cap those planets with high resources and bring you down with loads of shields and tricks up their sleeves. Especially DE/Eldar players with their kunnin' cards like Klaivex Warleader (they can kill your big fat Nob with Choppa/Rokkit Launcha by simply ambushing them during combat), sending you back home with Archon's Terror, or stunning your units with Eldorath. 

Most importantly, you do not have enough strong command units to capture resources and cards...a smart opponent will simply stall the game and avoiding fight, while collecting cards and money on the other planets while denying you at the same time.

You will definately have hard time against Eldorath or Kith where they can out-command you and choke your resources. In the end you will have too many expensive cards in your hands, but enough resources to play them.

The Orks need one thing to make them competitive now and that is a heavy command presence. Without command dominance they fall apart. With this deck, I don't see enough command to pay for your expensive units like your Nobz and Gitz. I also find that the Orks are big and strong how they are and don't need attachments to make them any better. I find it is overkill. 

I am curious to see your results in testing this deck.
