Pokémon Sword and Shield will be running a Shiny Magikarp New Year's event beginning December 31 through January 3. The event will allow players to have a much greater chance of encountering a Shiny Magikarp when entering Max Raid Battles in the Wild Area. The Pokémon website states:
Kick off the new year with more Magikarp appearing in Pokémon Dens in Pokémon Sword and Pokémon Shield for a limited time. The Magikarp you'll encounter in Max Raid Battles will also have a much higher chance than normal of being Shiny, so don't miss your opportunity to battle and catch this special Pokémon.
With the event only lasting until January 3 players have a very limited time to take advantage of the higher shiny encounter rates. There seems to be a running theme between Pokémon Go and Pokémon Sword and Shield and events that increase the chances of finding shiny Pokémon. A new Pokémon Go event is also coming up on January 7 that will increase the odds of finding a Shiny Heatran in that game's raids. It remains to be seen if Nintendo plans on creating events like Pokémon Go's Community Days that increase shiny encounter rates or if the will simply stick to specific Max Raid Battle Shiny events like this Magikarp one.
Other than these types of events Pokémon is also known for its events that are centered around new legendary Pokémon for players to discover, battle, and capture. So far there's been no word or even rumor about a new legendary event Pokémon, but with the new year just beginning there's plenty of opportunities to be had.
What other types of events would you want to see Nintendo bring to Pokémon Sword and Shield? What Pokémon would you like to see as the next one featured in a Max Raid Battle Shiny event?
