I think that for optimizing your deck, you need to respond these questions:
- What are your goals with the deck?
- What does your pocket meta look like?
- How does your deck perform in your pocket meta?
I think any advice would be futile if you dont have info about which decks you are playing mostly against and what you want to do with the deck (have fun, farm golden hero, climb up as high as you can, enhance some matchups of another deck of yours)
