How exactly does Psych Up work? Does it copy your opponent's stat ups or does it add onto yours? Let's say I use Swagger on an opponent and then I use Psych Up. So now I have an attack modifier of +2. If I use Psych Up again will my attack modifier be +4 or will it still be +2? Also, if my opponent used Rock Tomb on my Pokemon and lowered my speed, and then I used Psych Up, will my speed return to normal if my opponent had normal speed?
I am pretty sure that if you psych up a stat, it will use the modifier that the opponent has. for example, if you had -2 in speed for whatever reason, and you psych up on a pokemon with no negative modifiers, you would end up with 0 modifiers in speed. someone correct me if i'm wrong.
