How many turn dose it take to have timer ball be as good as a master ball?
It takes a really really really long time for a timer ball to work as good as a master ball, like 100-200 turns. But a timer ball can never be the same as a master ball bacause a master ball will automatically catch the Pokemon even if you don't do anything whereas there is still a chance the Pokemon will not be caught with a timer ball.
Best idea is to just use a master ball or to use an ultra ball. Ultra balls are really good as well :)
