I decided to use the WT Horsea I have. It's now a 31/31/xx/xx/xx/xx Seadra and I can always snitch more Dragon Scales. Just got Meditite one more level for Recover, and evolved. Ready shortly. :)
EDIT: Just added you (two more slots, time to delete people again soon LOL).
So...here's how I presume this will work. I trade Seadra with the Dragon Scale to evolve. You send back whatever you want to evolve. You continue doing that until you send Kingdra back, which will signal to me that we're done the trading session. Sound about right? :)
Let me know when ready and I'll come online.
