I'm already at Ho-oh, and I just found an easy Jolly 31/31/31/29/31/31 spread that I can use for Ho-oh. It'll even have a "normal" date and everything! ^.^ I think I'll go with it for this runthrough.
I was kind of wanting a Naive HP Ground 70 spread so it could dig into it's massive SDef and not really hurt anything and maybe even go Special to fool some people (switching in Intimidating pokes and whatnot). Ho-oh's SAtk isn't the greatest, but with HP Ground 70 it could cover all it's bases (Thunder, SBeam, HP G 70, Heatwave, etc...). However, I can't seem to find an "easy" spread, so I'll just put that off till maybe next time... :/
