I need helpon pokeball captures !?

Question

I need techniques on capturing Pokemon in diamond/pearl,i use down b but its not working on darkrai so i really need help.

Answer 1

You should have saved your Master Ball for Darkrai, but you might be saving your Master Ball for Girantina, or you might have used it against Palkia/Dialga. The only thing I can suggest is to get him down to red health. Then either, freeze or put him to sleep. Have at least 50 Ultra Balls ready, and a few Timer Balls and Repeat Balls if the match lasts a while. Then get to throwing once he is frozen or sleeping
