This is a really good guide Sciztar. You explain very well the points you need to help a person who is trying to make a Trick Room team. I like the idea you started on adding Recommended sets on the Trick Room users. You should also mention some types of teams that are threats to Trick Room. Stall Teams, Baton Pass, are some examples of teams that can cause Trick Room some problems.
Other than that this is a really good guide. A lo tof people will greatly appreciate this guide when this gets put on Smogon.
