he will use his
petal dance:
Petal Dance inflicts damage for 2 to 3 turns (chosen at random). Once selected, even if it misses, the user will only be able to use Petal Dance, and will not be able to switch out. At the end of this duration, the user will become confused.
If the Petal Dance duration is disrupted, such as by full paralysis or by hurting itself due to confusion, it will immediately end. The user will only become confused if Petal Dance is fully executed, without its duration being disrupted. Sleep, freeze, partial trapping, and flinching will pause but not disrupt the duration of Petal Dance
then he will evolve into a venusaur and solar beam their asses
solar beam:
SolarBeam does nothing on the turn it is selected, other than state that the user has taken in sunlight. On the following turn, SolarBeam will inflict damage, PP will be deducted from it, and it will count as the last move used. Once SolarBeam is selected, the user will not be able to switch out until it is disrupted or fully executed.
If SolarBeam is not fully executed, PP will not be deducted from it, and it will not count as the last move used. If the target uses Mirror Move during the turn that the user takes in sunlight, Mirror Move will copy the move that the user executed immediately before using SolarBeam (or fail if it can't).
Sleep, freezing, partial trapping, and flinching will pause but not disrupt the duration of SolarBeam.
