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.
I know that you mention Modest Nature on King Charizard set, but I see no examples there in which situations it's superior to Timid. So if I may ask for those situations ? :D
Oh crap, I still had this :(. Nah, I can't forsee myself even starting on this for at least another month, so yeah, I think it's best if someone else took over.
Just asking out of curiosity, why is there a mention of DD in the SD set usage tips and how it outspeeds Yveltal in webs? Perhaps you could phrase it better?
