I would if I could connect to the internet on my DS lite, I need to sort out my routers security settings 1st, I could get you a lvl 40 one from that dragon cave using my super rod, thats how I got mine, what would you want to trade for it?
What moves does a level 40 wild Dragonair start with?
The reason I am tempted to level up a Dratini from scratch is so it keeps some of the best abilities. If you get a level 40 one, it may have a lot of random ones that have no use.
