If you want a Shiny Clefairy, Pokémon Scarlet and Violet are giving you the perfect chance
Hunting for Shiny Pokémon in Scarlet and Violet is easier than in previous games in the franchise, mainly due to the mass outbreak system allowing for group spawns of one particular potential ally. Normally, outbreaks are random, but a set event will allow for Shiny Pokémon to be relatively easy to catch.
A mass outbreak event for Clefairy will be live all across Paldea in Pokémon Scarlet and Violet from Sept. 28 to Oct. 1, The Pokémon Company announced today. Not only will this allow for easy ways to find the Clefairy for your team, but the immense spawn rate will give trainers a higher chance to get that rare Shiny Clefairy.
