Rate my sapphire-steel list

In two locals i scored 0-4 and 1-3. The deck worked as i wanted but i felt it was too slow in end game (setting mufasa, dime or tamatoa is not the cheeper stuff). I tested this list with friends, taking statistics of win rate again various archetypes, and it is about 57%. So, my loses Is It only a case of bad luck?

What can i change? Someone sapphire-steel main/lover?
