As of the version 2.10.0 update, playing Main Story areas now does not consume Stamina. You can no longer obtain Rank Points in any Main Story areas, however first-time rewards and completion rewards will remain the same. The limit of Pokémon hatched from Eggs that you can keep in the Day Care is being increased from 200 to 500, and there are also several Moves and Passive Skills text improvements.
All Aboard the Victory Train
This event introduces sync pairs for Ingo and Emmet, the Unova region's Subway Bosses.
Ingo and Excadrill are a Support Sync Pair. Their Passive Skill allows you to nullify damage from sandstorms, and the Defense and Sp. Def will rise during a sandstorm. They have a move called All Aboard!, which raises the Attack and critical-hit rate of all allies, and it applies the Free Move Next effect to all allies if used during a sandstorm.
Emmet and Archeops are a Strike Sync Pair. They have three Passive Skills; one that nullifies damage from sandstorms and boosts the power of the Sync Pair's moves during a sandstorm, one that increases the move gauge cost of moves while boosting their power, and one that increases their Attack by 50% when their HP is at half or above. They have a move called Right on Track!, which lowers their Defense and raises their Attack and accuracy. It also applies the Damage Guard Next effect.
This event has already started, and will end on July 14, 2021, at 10:59 p.m. PDT.
