So, I assume that the same works with all speed-changing moves (Agility=sharp drop in speed, Hammer Arm=Boost in speed)? Okay, thanks, I was really wondering about this.
Follow up question: how exactly do the mechanics of TR work? As in, how is speed determined? Is it inversed, and how so, since numbers go up to infinity and you can't have negative speed, or does speed stay the same and the game just looks at it like, "Okay, this pokemon has lower speed, but Trick Room's in effect, so it will go first", but if it does, then how does it work with speed boosts if they do like you said?
Also, Choice Scarf would make you doubly slow in TR, even if you went into TR with it on, right?
