I know I'm derailing the thread, but.........
Got started in the VGC community in Gen4 and specialized in Double Battles/VGC Rules from there (no spike or toxic stalls here
). Last World's event attended was Vancouver Canada and played for Team Magma. I am not fond of Trick Rooms and prefer to shut them down before they're ever set up. I definitely prefer VGCs where Ubers are banned and if possible, teambuild around Volcarona.
Even after reading tips and tricks about RNG manipulation, like shinies, I could never fully comprehend it, so I stuck with good old fashioned breeding. Heck, the equation for a pokemon's catch rate varying on the type of pokeball used was easier for me to understand.
Just got get us a bit back on track, it probably is a good idea to keep an eye on Moarsi, if you're looking for good RNG. Moarsi is an awesome person, but I have so much jelly directed in that specific direction for single pulling all the girls I have my eyes on. So much.........I still need to get that Anthurium! And Oxalis!
