I used to do karate too, way back when I was about 9 or something, so there wasn't very advanced moves etc. :) I like martial arts too, one of the reasons I love Sawk. I like using him in OU for the lols, and most people from OU have never played NU before so they have no idea what's coming xD
After you go to the time finder, you paste your full seed into the main window. Make sure that you have the Method set to Method 5 PIDRNG in your main window. Also make sure that you have the Encounter Type set to Stationary Pokemon. If that doesn't work let me know.
