You need the national pokedex.

In Ruby and Sapphire yes you need to beat the Elite Four first, but in Emerald you can catch Raquazza before or after you beat the Elite Four.

No
You need to beat the elite four and then beat the Pokemon league champion
Well it depends what game you have. And if you want the Black Trainer Card, then you need to beat the Elite Four 6 times before you get the black card. After you have beat the Elite Four 6 times you get your BLACK CARD! :)) I already have it :))) <33
You don't need pokemon, you just need to beat the elite four and have the national dex (which you should get after you beat the elite four, because they have kinda rare pokes)
You need to beat the elite four and get the national dex.
