Try to get a Secretkeeper on the board early.

Either through draw with Divine Favor (have as few cards in hand as possible) or Hidden Wisdom or she will be pulled out of your Deck with Call to Arms 100% of times.

Next step will be to buff her by playing your secrets which will also help her stay alive: Autodefense Matrix, Noble Sacrifice, Redemption

Righteous Protector and Giggling Inventor will also help your Secret Keeper to stay alive and Righteous Protector will be pulled out of your Deck together with her.

Subject 9 is just another draw engine and could be easily replaced with Electrowright.

The rest of the Deck just tries to get some Dudes on the Board as another win condition. They will also be protected by your other Cards.

Other Cards for replacements in this Deck are: 

• Electrowright, cause you have 2 Call to Arms and 2 Level Up! which both will be stuck in your hand sometimes.
• Sword of Justice to buff your Minions
• Prince Liam for a little desperate Win condition as he will turn all your Secrets into random legendarys
• Vicious Fledgling cause it's still strong

I personally created this Deck because I wanted to play Subject 9 but like I said it's not a mandatory card. Often times you will find yourself with too many cards in your hand anyways because of Divine Favor and [card]Hidden Wisdom/card]

Have Fun trying this Deck!
