Does power trick switch base Att and def?

Question

I want to know if power trick exchanges the base attack and defense or if it is still effected by increases and decreases. For example: shell smash decreases the defense by one stage, but increases the attack by two stages. Will my new attack have the decrease of one stage since I activated shell smash before the switch, or will it have the two stage increase?

Answer 1

Power Trick switches the user's Attack stat with its Defense stat, however any boosts or reductions that have been applied to those stats are not switched. Using Power Trick again will remove the effect.
