Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
The only thing I don't know is how to get the seed using that sheet. I see everything except the Seed in the chart and configuring the pikatimer to have enough time to load the 100% catch code using the homebrew Nitrohax. xD
I guess I'll pick the Mixed Attacker one (since I only have a Mild synchronizer) xD ...but I'm kinda confused on how to RNG it. I already abused my ID/SID, I have OmegaDonut's high IV shiny spread sheet.
