I somewhat agree with PenguinX about the limited options of Trick Room teams, provided the few users of Trick Room. I however fully disagree with the statements of its inevitable failure. I believe there's a lot of room for exploration left in Trick Room, and barring Stall, a solid Trick Room team can be crafted that will be competitive at any level.
Trick Room is where it's at, you bitches. Trick Room all day, e'eryday.
