Going well, 5 gyms down. I tend to lose exactly once to most of the gym leaders, which makes sense, since they've usually got a trick that's relatively easy to deal with once you know it's coming. Also, compulsive breeder that I am, I usually try first with an egg and a "project" (underleveled unevolved) in the party.
Exceptions were the grass and water gyms. Grass just seemed pansy, water I went in (for whatever reason) better prepared, with Leafeon instead of an egg and Kirlia instead of a project and steamrolled despite numerous tactical errors.
Core party is Prinpulp, solid defensively, decent offensively workhorse move is Bubblebeam, also carries my Rock Smash.
Roselia for relatively low defense massive draining offense and Cut. Poison Point is pretty cool, too.
Staravia continues pretty cool, Fly plus Aerial Ace (and Defog, which I really want to just forget and slap on some stupid filler for whenever i need it)
Luxray is hogging the spotlight right now as my first 3rd tier pokemon. His Bite carried me through the ghost gym, funnily enough, and he's got my highest raw offense generally with Spark, too.
Adjuncts include Bronzor (defense plus status is almost enough to make up for an inability to do damage). Kirlia (total project, decent offense but nothing else, about to evolve which'll help), Driftloom (mostly dropped, just wasn't performing), Togetic (similar) and Ponyta (more boring than underperforming, but I hardly use it anymore), Chimecho (evolved and dropped).
Breeding Eevees right now, might hold on to Espeon, Glaceon or Flareon for reals, haven't decided. Don't really fit the theme, though, so I might talk myself out of it.
