I would use either an ultra ball or dusk ball.
master ball
The best ball to catch Giratina is the Master Ball but the next best and effective options would be the Dusk Ball or the Ultra Ball.

Ultra Balls.
You use a poke ball, great ball, ultra ball etc. To be honest I think the best ball for Palkia is an ultra ball. It's really easy to catch so don't go wasting your master ball on it.
Master Ball is the best but I use the Dusk Ball and it worked==:COMMENTS:==~Silver*: Duhh? Master balls can catch any wild Pokemon -.-ll
You get their health really low and use a ultra ball the best
Use a master ball.
