Personally, I've soft resetted some Legendaries. Especially notable are these two guys:
Politoed666 's Arceus, Lv.100; Rash Nature
Fateful Encounter, Pokémon Event; OT is TRU
IVs: 31-29-6-18-27-28
EVs: None, of course.
Judgment, Roar of Time, Spacial Rend, Shadow Force
Politoed666's Darkrai, Lv.50; Mild Nature
Newmoon Island; OT is Fagan
IVs: 5-27-7-31-31-27
EVs: None.
Hypnosis, Ominous Wind, Nightmare, Blizzard
The Arceus is my TRU Arceus. it's at Lv.100, of course, and as such will never really be useful. However, I spent a few hours SR'ing it and I'm happy with this spread. As for the Darkrai, it's a damn fine Choice Scarf mixer.
Additionally, I had a friend from a different forum do a couple breeding projects for me recently... I'm thrilled with the results.
Politoed666's Makuhita, Lv.1; Impish Nature *shiny*
Egg Received Dec. 6, '09; OT is Justin
IVs: 31-31-31-22-31-31
EVs: None
Tackle, Focus Energy, Wake-up Slap, Endure
Politoed666's Shieldon, Lv.1; Relaxed nature *shiny*
Blah blah blah
IVs: 31-31-31-23-31-0

Blah blah blah
Nice stuff.
