Well, I played a little more of Final Fantasy XIII-2, and basically did a chapter or two before taking a break at the next part that opened up a couple places at once, because I couldn't decide what to try doing first. ^__^; After that, I popped in Legend of Zelda: Skyward Sword again, and made some progress there as well (though when I consider the fact that I've mostly been wandering around the current part of the world and haven't even gotten into the dungeon proper yet, it doesn't feel like much progress at all).
I'll admit, I had to read that a few times to make sure I understood it all properly, but that Suicune does sound like quite a beast. I -would- wish you luck with Sheer Cold actually hitting, but I think I'd rather hope that Suicune doesn't face any foes that it would have to rely on that attack to defeat. xD
Yeah, I need to get back into Skyward Sword myself. At the very least, it's good exercise.
Now, because of the way that the accuracy for One-Hit KO moves is actually calculated:
(User's Level - Opponent's Level) + 30%
For in-game use, once you reach the level 100 cap, it'll actually be hitting fairly often. The only places where it might still give me trouble are the Battle Subway or the Pokemon World Tournament where-in all pokemon levels are set to level 50 so you only have that 30% accuracy to depend on. And even then, Suicune is still bulky as all hell so with that outstanding survivability it might still manage to pull it off, possibly even in its sleep. I think Suicune pretty much exists to take a nap and destroy the opposition.
