So, after I spent all day yesterday soft resetting to get the shiny Gible that is given as a reward for clearing the Black Tower with a desirable nature and sensible stat spread (namely one that doesn't favor special attack) and finally got what I wanted (Jolly with a perfect attack IV) and effort trained it in attack and speed, I went off to do some serious level grinding whereupon I encountered a shiny Sawk partnered with a normal Sandslash in a wild double battle. Naturally, I captured it as the newest addition to my shiny pokemon roster and also the first shiny pokemon to be captured in Black Version 2. I think this might confirm my hypothesis that the most efficient method of finding shiny pokemon is to just play the bloody game.
Yeah, struggling to come up with a suitable nickname for it though. Been trying since yesterday because I decided "Brawler" is a bit too generic and doesn't really fit with the Impish nature or the "Likes to relax." characteristic it has.
By the way, my minutes did finally reset for December so we can chat on the phone again if you're up for it.
Alright, it looks like my internet is finally more or less stable again. I think I'm even more annoyed when my computer can stay connected, but somehow fail to load websites 99% of the time, than I am when my computer can't load anything at all.
In any case, things seem to have stabilized, including (if the fix I did last night actually works properly) my laptop no longer having a small but annoying chance of getting a Blue Screen of Death whenever it comes out of sleep.
