Pokemon weather problem

Sunny days: fire attack power increased by 50%, water attack power decreased by 50%, rainy days: water attack power increased by 50%, fire attack power decreased by 50%, sandstorm: rock physical defense increased by 50%, except rocks, steel and earth, the maximum damage of attribute monsters per turn is HP116, hail: attribute monsters other than ice attributes. 16 fog injury: the hit rate of monsters on the field decreased by one cycle. If both sides issue PM that can change the weather at the same time in a battle, the fast monster will start the effect of changing the weather first, and the slow monster will start the effect of changing the weather again. I was chosen because I typed hard.
