ZitatWhen a Pokémon with Pressure is targeted by a foe's move, one additional PP is deducted upon execution. Consequently, extra PP is deducted even if the foe's move misses, has multiple targets, or is rendered ineffective due to immunity. Pressure applies to allies targeting the Pokémon.
Nach Bulbapedia sollten mehrere Pokemon mit Erzwinger bei Multi-Target-Moves sich stacken. Jedes Mon mit Pressure zieht also einen zusätzlichen AP, was maximal 4PP pro Move macht.
