Hi,I am new here so if this is the wrong place to post it then sorry.
Ok there are two ways to catch an eevee on Pokémon Diamond.
(1)This is the first way.
First of all you need to make sure you have completed the sinnoh dex,which contains all 150 pokemon.
Then go to Professor.Rowan and talk to him,he will then give you the national dex and poke-radar.Once you have them use 'FLY' to get to Hearthome City,you will be dropped off outside of the pokemon center.There is a building right next to it,go inside it.You will find bebe who made the pokemon storage device available.so talk to her and she will give you an eevee(if you have a space left in your party.)This is the easy way.
(2)The other way is alot harder.First go to Mr.Backlot's Mansion.
you will see a maid stood outside of his office go inside it and agree with everything he says.you might have to try this alot of times so i would advise saving it before talk to him.and if you are lucky he will say there is an eevee in his garden.if he does go into the trophy garden, and use your poke-radar.This might take a while but you will eventually find one.
Hope this helped.
