I have not been able to get a Gold Hero in the Tavern for a Very Long Time.
I was up to 8,586 Spirits and in all that time to get there, I have not flipped a single Gold Hero and Very Very Few Purples.
I Spent 7,500 Spirits on 5 Adam Card, Today and only one Failed

I like the Double Spirits but the chance of getting a Gold or Purple Hero is Very Small.
I am Level 105 and I do not have a use for any Blue Heroes.
