If Mew VMAX uses its "Max Miracle" attack against the opponent's Fusion Strike Pokemon while the opponent has an Oricorio with the "Lesson in Zeal" Ability in play, does "Max Miracle's" damage get reduced or not?
The damage reduction of Lesson in Zeal is considered an "effect on the Pokemon". Max Miracle ignores ANY effect on the opponent's Active Pokemon, so therefore Max Miracle would be able to overcome the effect of Lesson In Zeal.
