You get it by going to the master and getting his balls☺.......... Just kidding .you really get it by.............. nah......i don't know
no you only get one dont use it untill you beat the league then you can catch mewtwo
Use master balls. Use a ton of ultra balls and put them to sleep or paralyze but master balls are your best bet since leaf green is harder than its original counterpart
You can't buy master balls. Unless you get traded a Pokemon holding a master ball, you only get 1; and that's when you beat the team rocket boss in silph co.
