i checked bulbapedia and its says >> (If the target also uses an increased priority move during the same round that the user uses Sucker Punch, the attack order of the users will be determined normally. )kaiser6tn said:Yes, sucker punch will always fail if a faster (I'm assuming that mamoswine got an ap boost earlier on that battle) opponent uses a priority move.
kaiser6tn said:There is one very simple argument to support that change, pwo uses gen 5 for reference on what concerns battling (power and accuracy of most moves, moves a pokemon learns by leveling up, tms and so on). So knowing that, why should priority moves be handled any differently?
