That means it's better for us to fully unlock the available hidden power before evolving to higher rank, as lower rank card can relatively be obtained easier and cheaper.

e.g. I have already evolved my Hakua to S rank, and he has 5 hidden powers. When using identical spirit with the same rank, that means I have to have S rank Hakua x5, which is very expensive and time consuming for getting evo spirit.

Instead, when I get an A rank Hakua this time, I fully unlock the hidden power before evolving to S rank, and then use my un-unlock (......) S rank Hakua as the "enhancer". It will safe more time and G used.
