Nature Influence

This can also be like Nature Mints in pokemon Sword and Shield. This is 100% chance so using an Adamant Mint on a pokemon WILL ALWAYS result in that mon having this nature. To balance it out it could be pretty expensive but not too expensive. This is becuse unlike Everstone this is 100% chance not just a high chance that can stil fail. Good for when hatching a melan after a million eggs just to discover it has the wrong nature. Just use the correct mind for that nature to save you time and not hatch another million eggs only to find out it has the wrong nature again Even better if you want a full line. But this will make nature hunting very easy as any offspring you get you can simply buy that mint and chance its nature. Here where the expensive price comes in play so you cant just buy a million of them and change every shiny albino or melan you get to have your desired nature. Note that this only affects the offsprings as the parents most likely already have that nature/holding the everstone. This is for every offspring you get that has the wrong nature and you wish to change to it.

This is implemented for Valentine's Week, and should be implemented for future events. However, outside of ZC shops, the RNG of it allows a trade market to continue. Edit: oops, I got this suggestion mixed up with another! Well, you have my opinion, but I'll leave this open to discussion :)
