For aesthetic and programming purposes, fix the set into this:
name: Expert Belt
move 1: Secret Sword
move 2: Hydro Pump
move 3: Icy Wind
move 4: Hidden Power Electric / Hidden Power Bug
item: Expert Belt
evs: 4 HP / 252 SAtk / 252 Spe
Also, I've been secretly experimenting with Rain Dance Keldeo before this was approved, and it's actually pretty fucking awesome in actual PS gameplay. So at worst, it deserves an AC mention, but not a slash.
Outside of that, this has a likely chance of being approved, so keep an eye out today.
edited: fixed your title, too.
