Diancie movesets and Super Training help, please?

Okay, so I just received my Event Diancie today from Mystery Gift(via Serial Code), and I was wondering if any of you guys can suggest a moveset and EVs and IVs for her(since I’m new to competitive Battling, can you guys be specific, please? Thanks!).Diancie’s Info:Currently Lv. 51Has a Jolly Nature, raising Speed(which is good), but lowers her Special Attack(I want her to have Special Attacks and Diamond Storm, I want to balance her EVs and IVs for this)Her Ability is Clear BodyAs of now, she knows:Reflect(Will most likely be removed)Hidden Power(Rock, sadly, so I’ll remove this)Dazzling Gleam(STAB, coverage of multiple Pokemon)Diamond Storm(STAB, signature move)Here’s a moveset I found on a GameFAQs discussion:“seeing how its speed is major crap, I guess Sassy(+spd -spe)252hp/252atk/4spa-stealth rock-diamond storm-moonblast (why cant this thing play rough)-light screen/reflect/toxic”

Okay, here’s my second problem. If I want to Super Train my Pokemon, how many EVs/IVs does a Large Stat Bag give, and how many Large Stat Bags can one Pokemon use in total before their Stats are maxed out? I want to know more, so can you guys tell me how Super Training works specifically with Stats? Thanks a bunch!

Pleaselog inorregisterto add a comment.

Here’s a Diancie set, which makes use of it’s excellent defenses and mixed attacking stats:

Diancie @ LeftoversAbility: Clear BodyEVs: 252 HP / 4 Atk / 252 SpAQuiet Nature- Stealth Rock- Diamond Storm- Moonblast- Hidden Power Fire

As for your Super Training question, Large stat bags give12 EVsin their corresponding stats. To max out the stat (252 EVs), you’ll need to you a whopping21Large bags.However there is an easier way, in Horde EV training. See more about ithere.

Hope I helped!
