4th Gen A new team

Hello again well I was thinking about trying to make a tough eevee evolution team I havent made an eevee team since gold and silver and since there are lefeon and glaceon I was thinking what the hell lemme give it another shot so can anybody throw me some ideas formy team and where I can get firestone waterstone
and thunderstone in diamond your comments are appreciated thank you.

I just want to know if this is a good idea and what I should do, if not I'll just continue with the team I'm working on.

Eevee teams are useless as they each have one type only, where in this game you need your pokemon to have two or more types, at least if you want them for wifi.

The evolution stones are found either by digging underground, or by using a pokemon with the ability Pick Up and it's level 50 or more

i am not sure but shouldn't this be in stragedy and movesets?

Yes, this should be in Strategies and Movesets.

There are much better Pokemon to use than the Eeveelutions. However, if you want to challenge yourself and see how well you can do with it, go right ahead.
