1. When it is already S rank? Like for many of the veteran players?

2. When you don't want to wait a million years (or spend $$) to get duplicates of that card to use for unlocking powers?

3. When you want to evolve the card and actually use it in your deck?

And the most important one, hidden powers are not all available in the first rank, e.g. Coffy (Wild Gunner) has only 1 hidden power available for unlocking while Coffy Strife (Wild Dual Pistols) has 4.

Possibly there are more, but I don't feel like listing them all down.
