yes you can. Although I would suggest having tons of them and make sure you save before battling it. Although if it is one of those that you need to find in the wild somewhere, then you need to have a Pokemon that knows block so then it wont escape. Also for both theries have Pokemon that are LVL 45+ as the Pokemon is extremely powerful.
Hope this helps.
First you have to beat the game. Then you need to complete the solar cave. This will introduce Spinda and the tale of the mirage pokemon. You will get the clear wing(it wont be in your invintory). Take this to Xatu at its home in the hill of the ancients. This is reached by clearing the great canyon dungeon. The fiery field will be opened. You can't recruit entie the first time through. Instead, you beat him, and it opens lightning field.
Well, you can practically catch any pokemon with a great ball, just that it has a very small percentage of getting it on the first time. Even if you are trying to catch a legendary pokemon, it is just the matter of time before you catch that pokemon/legendary pokemon you want!
You can catch it at the Pastoria Great Marsh.

If you catch a Pokemon when your party is full it will automatically be sent to the Pokemon Box storage system, isn't technology great?
