Effect
After the Pokémon successfully uses a move against a target, it has a chance of lowering one of the target's stats (Attack, Defense, Sp. Atk, Sp. Def, Speed, accuracy, or evasiveness) by one stat rank. The skill can range from Grab Bag 1 to Grab Bag 9, with higher numbered skills resulting in a higher chance of lowering a stat. Grab Bag 9 will always lower a stat. Currently, only Grab Bag 9 is available on scoutable sync pairs. The effect applies to all of the Pokémon's moves—including attack moves, status moves, and buddy moves—but not sync moves or max moves.
