I hate to post twice in one day, but...
First of all, congrats to stardog_champ on Purugly, camhines4 on Duskull and Seviper, tonyg44x on Nidoran and Farfetch'd (and welcome back!), and to anyone else I missed!
Before I mentioned the rain at Virbank Complex, and how it was an utter pain as it slowed the encounters a lot, but after doing 500 REs at my favourite place the Valley Windworks, I decided to switch it up a bit, and get up to 1500 at the Complex. Needless to say, that didn't happen, as on the 1,446th encounter...
Shiny Elekid! I was happy getting anything in this area, except maybe Patrat as I'm bound to come across a shiny one of those at some point, but I got one of the area exclusives from this place! The sparkles made me jump, and honestly I'm glad they did - there's very little difference between the normal form and the shiny form of these guys, even though when looking up the sprite on the internet I thought I'd easily be able to tell the difference, but nope!
I named him Bulb, and he got a Naive (!!) nature which really benefits that line's speed. I already decided to EV him in speed and sp. attack, regardless of his IVs - but when I plugged them into a calculator, his Sp. Attack had median 20, and his Speed median 24, which were his two best IVs! He's going to make a pretty badass pokemon to say I randomly encountered for him.
I only started this hunt two days ago, and barely touched it yesterday, so I'm happy White 2 gave me a quick shiny. I'll be staying here until Winter switches over (about 10 days), when I'll go hunt Cubchoo on route 7.
I also updated my shiny card with both this guy and Skitty - I also added little symbols relating to the games I found them on!... which leads to the bad news - I didn't realise until adding them that my brother reset his Pearl without me realising, so I lost a shiny Budew. I'm keeping her on there, because that hunt absolutely sucked, but I don't really mind too much since I have two other Budew plus Roselia plus Roserade from the wonderful Eterna Forest.
Anyway, good luck everybody, especially CpChris and Razorbadger!
