I don't think I can give you any advice, because I've never battled anyone here on smogon, not even once, and more likely I'll never battle, because even minor issues in wifi can cause major problems in smogon, especially there are some members who are too hasty to report someone for DC'ing (even if it's from wifi, and not the player who did it).
All I know is why there are a lot of Trick Room Suicune out there is that the Event Suicune always has a Relaxed nature, which is a -Speed nature anyway...
As I own a flash cart, I already played it through on a translated version. Lost the .sav, though. Now, I'm playing again, but to use it here, so I'm using a purely japanese version. I can't understand a single thing when it comes to entering DW. D:
Gimme a hand here: should I go for a TR Suicune or a near flawless one? I'm getting HP Ground no matter what (-Red-'s idea), but I don't know what to do now. TR Suicunes are everywhere! O_O
