Another limited-time event is going on in Pokemon Masters EX, and it involves egg hatching. Check out the official announcement on what's available below.
Through November 4, slide into Pokémon Masters EX for an exciting Ice- and Fighting-Type Egg Event. During this event, look to train up your Ice- and Fighting-type sync pairs—they'll come in handy when facing the toughest challengers.
After the battles are over, Pasio's Professor Bellis will reward victorious Trainers with Eggs. Trainers can improve their Egg rewards by adding the player character to their team and by forming a team with sync pairs who have supereffective sync moves. Some of the Eggs could contain Lapras or Mankey, and Trainers may have a chance of obtaining a Lapras or Mankey that's Shiny!
