Hey Blueforce,
Typically I only nickname the Pokemon I use for playthroughs, as well as special Pokemon that I've bred or RNG'd. I don't trade nicknamed Pokemon usually, though.

Thanks in advance for the giveaway!
P.S. Love the nickname to bits, if only for its association to Madoka. Mew is an incredibly fitting recipient of the name though, even though I don't think it's ever done anything canonically quite to warrant association with the flag bearer of evil cats :)
