I have an announcement of utmost importance.
Three days before the release of X and Y, I started a fun debate with
this post over whether or not Shadow Tag Chandelure exists. It went on for several pages and with several members.
When I beat the Elite Four and got to the Friend Safari, I found one of my safaris had Lampent. I was excited to catch a Lampent with Shadow Tag but resigned to the fact that it may lessen my argument somewhat, as I wasn't expecting such an easy way to obtain Pokemon with hidden abilities. My main tactic to find one was to just run away from the battles and see if I got caught or not. After a while of doing this with no luck, I got fed up and on a whim looked up Lampent in Gen 6.
Imagine my surprise when I learned that, as of Generation 6, Lampent and Chandelure
no longer have Shadow Tag as their Hidden Ability. Instead, you can catch Lampents with the ability Infiltrator in the Friend Safari and evolve them into Chandelures with Infiltrator.
WHAT DOES THIS MEAN?
- Mega Gengar is the only ghost that is gonna rock Shadow Tag.
- Shadow Tag Chandelure will never, ever exist.
- I was completely correct with everything I said and you will all seethe.*
*Serperior was also included later in the debate but it started with Chandelure so I'm not gonna count it. 
And i have been searching for it the whole time 
Can we trade later tonight though? I'm at work 
I will trade one of them
ask me in 5 minutes if you still want to battle
