Changes to make shinies better:

[elfin orchid]

• Give all units a shiny variant; as far as I'm aware, the only units that have shinies are mythics, secrets, and exclusives (+takarada and sakura) These shinies could just be simple color changes but it would be nice to collect some of them
• Add don't autosell shiny setting; if all rarities get shiny variants, there should be an option to autosell the lower rarity ones or not (please also add autosell low rarities with traits)
• Transfer shiny features; If you have two of the same unit (one shiny one not), it would be nice to be able to transfer shiny onto the non shiny one because if pull a shiny variant after already building up the non shiny variant, you should be able to use the shiny variant without having to build an entirely new unit
• Remove shiny feature; Like in anime adventure, you should be able to remove shinies for trait rerolls (Ex: legends = 1 trr, mythics = 5 trrs)

I agree with the remove shiny feature, the Autosell one. Rest aremeh
