Renoir, in order:
Jolly actually works better for me anyway, so that is a definite plus. And no EVs works fine for me.
Haxorus I can fix up pretty quickly with EV berries, but thanks for letting me know the EV spread.
Unfortunately I don't have a shiny Pokemon from that line.
Your Larvesta, Arceus, and Darkrai are ready and waiting for when we can trade. The Darkrai has a lowercase nickname and its IVs are somewhere around the neighborhood of 3/1/14/29/17/31. It's also Timid and has no EVs. Arceus is Serious nature with no EVs and its IVs are unknown save for a 31 in SpDef. (I didn't check it yet.)
The next time I'll have Wifi access is Sunday night after 9pm my time, which equates to Monday morning after 6am your time. (However after that I have Wifi access on and off pretty much the whole week, so if I'm on chat and it isn't the weekend I'll have my DS ready.)
