it doesn't matter what kind of pokeball you use it matters how long you take you can catch it with a pokeball as a last resort
Use yo head.
I used Tyhplosion,Staraptor,Starmie,Mewtwo,Arecus, and Giratina
catch a murkrow make sure it stays at level 17 or 18 and only use the move astonish because none of mewtwo's moves will work on murkrow
use a master ball on it
you know lengendaries are hard to catch,but some are normally hard.just use dusk ball or ultra ball
yes it is the strongest Pokemon not counting arceus event use it on mewtwo and win every battle beat the elite four with it 50 times in a row with him don't use it on him u r a mother $*?@! hoped i helped
use a pokeball and capture professor oak then sack him, then he gives you a mewtwo
First, capture a Ralts from a Pokemon Swarm (or trade from someone else). It must be a male Ralts. Then, evolve it into a Kirlia. Then, use a dawn stone to get a Gallade.
use a pokeflute
use the pokegear
you have to get a white flute
it's not possible:(
