Since my last post I dexnaved the following shinies
Magnemite
Electrike
Vulpix (9 Vulpix encounters after the first shiny Vulpix, but overall 200 Growlithe encounters as well as a few Shuppet's and others on Mt. Pyre.)
Psyduck
Porygon
Growlithe
Shuppet
Lillipup
I'm currently working on waternaving Seel and cavenaving Slowpoke, both would be my first dexnav shinies on water or in caves if I found them. Waternaving isn't that hard, my longest dexnav chain for Seel was like 39. I know chaining doesn't matter in dexnaving but I like to chain on water as having it be faster kind of makes it more fun. However chaining is terrible in caves. So instead I just run from the Pokémon then hop on the bike to get a new encounter. This works well on mirage spots where I can't leave to heal and don't want to waste leppa berries. And there's like only 2 Pokémon there.
