Any.
MASTER BALLS!
get alot of timer balls and ultra balls, about 50 ultra and 50 timer.use about 20 to 40 master balls on him then keep using timer balls on him(make sure you get him to yellow or red health).
you need to have two master balls.
Arceus has a catch rate of 3, so you need LOTS of Ultra Balls. If you have a Master Ball, you can easily catch it. He is ridiculous, because it takes so long to catch him! I recommend master balls!
Well to get Garitina use the master ball to catch Garitina or some dusks balls or timer balls or some quick balls.
yes first you go to stark mountin and catch heatren then you go to iron island and see cresslia it will flee then look at the poketech app that tells you where fleeing Pokemon are then chase it and catch it
gatch them with a master ball but trade the master balls
On a certain Pokemon that you want to catch and it's hard to catch it with just a Poke Ball, a Great Ball, or an Ultra Ball. I don't know where else you can get Master Balls besides the Silph Co. I usually use the Masterball on legendery Pokemon.
Master Balls, obviouslt
use the action replay to get 999x master balls
You buy some lots of master balls and then when you find a phanphy, catch it that's alll.....
There are many types of PokeBalls you could use to catch Azelf.But I would suggest the following: Quick Balls Master Balls Poke Balls Dusk Balls and,Ultra Balls
