Restores [X] MP for the user the first time its sync move is used each battle.
Sync Burst (Japanese: 初B技後技回数回復Move Points Refresh After First Buddy Move) is a skill in Pokémon Masters EX.
Effect
The first time the user's sync move is used in battle, MP is restored to each of the sync pair's moves that have MP. This includes both the Pokémon's moves and the Trainer's moves. The amount of MP restored is equal to the skill rank, though only Sync Burst 1 is currently available on playable sync pairs.
