2 All My Knowledge....You Can't...
you cant get a timer ball in emerald
Yes it can because after ten turns in battle you can use a timer ball and it will mostly work without fail.
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 :)

You can't get another master ball in emerald because there's no one will give you the master ball just the general will give you that.
The best ball to catch Deoxys is a Master Ball or a Timer Ball! Trust Me!!! Pokemon Master
