Okay so this idea is that once you buy a dye kit and apply it to a creatu, it will remain in a drop-down menu just like effects do. That way we can switch up our creatu colors at whim. Also, it is an incentive to buy dye kits to apply to creatu, having the goal of all colors. So it definitely wouldn't wipe out the market for kits.

How about they create a reverse dye kit,

Halloween, what benefits do you think your idea would have over the original idea?
