You need Pokemon from the previous versions of Pokemon such as:Bulbusaur, charizard, Jigglypuff, Wiggltuff, sorry those are the only Pokemon I remember except for some legendaries and Ekans and Arbok, try a lugia.

You can't, it's not possible.

Catching and Trading.

yes
You have to breed electrabuzz after catching one on route 222.
A master or ultra ball is good.
You need to have a GBA or GB game that is Pokemon and of Kanto or Hoenn, and put it in your DS. Then put platinum in too. Go the the main menu of Platinum and it will say something like "Migrate Pokemon from Pokemon ______" (whatever Pokemon version you have - Emerald, Red, etc.) And click on the link. And you have to migrate six Pokemon from that version to Platinum and have to use those Pokemon to be in a Catching Show. Hope this helped! :)
You can't 'see' an umbreon in Platinum. You have to level an eevee at night, or make it friendly. That counts as catching it and seeing it.
He means migrate six Pokemon from a GBA game. When you have he lets you in simple! :)
