In most cases, the Shiny Pokemon looks very different from the normal Pokemon. Many players like to buy from PKMBuy. Like Magikarp, it normally looks orange, but the shiny looks golden yellow. But there are ones like Pikachu where it's just a slightly paler shade of yellow and Gengar is purple and the shiny version is almost the same shade of purple.
In general, there are many ways to increase the chances of seeing shiny. By simply trying to catch Pokémon and seeing if they display as an alternate color in the battle and post-battle screens, you can find the Shinies. They will not appear in different colors in the field, so you must try to capture them first.
In addition, you can use two systems to significantly increase the shiny hunting missions. They are very simple, but if you follow these tips, you can almost double the chance of seeing Shiny Pokemon in the wild. What matters is how difficult it is for you to find these creatures. But this will waste a lot of our time, so I usually choose to buy on the PKMBuy website, it is very professional.
