Ferrogolem seems bugged right now. It is not removing the card from the deck when it draws... so you can get infinite firebrands with this.
As proof,
You can consistently fill my hand with lobotomizers or eternities with this deck:

Posted this to bug section too...
Don't know if this is intentional or not, but your ferrobrand deck would make for an amusing abuse of firebrand if it is.
