im pretty sure that you'll find one somewhere at route 212 and if not then keep fighting every trainer you see until you find one. happy to help! or hth for short.
In Pokemon Diamond/Pearl, you find a old man at route 212 with a Leafeon.
Where do you find a trainer who has a glacion in pokemon platnum?
In a battle at the top of Route 212
Get an Eevee and level it up in the Eterna Forest.
to get a leafeon in Pokemon platinum, you need to have an eevee and then at any lvl you have to use a leaf stone!
easy on the rainy route, there are two trainers they will ask for a double battle and wham there you go. if not evolve eevee at the rock in eterna forest
A trainer on route 221
You can't.
In the city!
ice type trainer in snowpoint
Theres a trainer on route 209.
No one has a Leafeon. You'll have a chance to see one in the Battle Frontier, but it won't go in your Pokedex or anything.
