Using a Master Ball.
The Master Ball is easiest of course but there are other Pokemon that are harder to catch so you might wanna save it for them. You can also catch it with a Dusk Ball or an Ultra Ball but his HP will have to be very low and it would help a great deal if he was asleep. So the easy way = Master Ball Hard way = Ultra Ball or Dusk Balls
you have to catch it with a dusk ball,ultra ball ,quick ball or a master ball hope i helped
Master Ball which you can get at the (Team Magma or Team Aqua) hideout
use master ball or weaken it,paralyz or make it to sleep
The other way of getting a legit Master Ball in Pokemon Pearl/Diamond/Platinum is through the Jubilife City Lottery. Winning the grand prize gets you ten Master Balls, however the chances of winning are tiny. The easiest way would be to use Pal Park and import Pokemon holding Master Balls from Pokemon Ruby/Sapphire/Emerald if you have a DS. If you have a DSi or don't have the GBA Pokemon games, then borrow a DS and/or game from someone else. Another (less legit) way is to exploit the GTS glitch in Pearl/Diamond and clone a Pokemon holding the Master Ball.
In all games its easiest with the master ball next if you can keep the battle going long enough the timer ball.
well try to get his health low and use the best balls! like the net ball master ball ultra ball!
