well, I would save the master ball for latias/latios. so, use the timer ball. or just palin poke balls, like I did.
Latios, since rayquaza does not run away.
The best ball to catch Deoxys is a Master Ball or a Timer Ball! Trust Me!!! Pokemon Master
In order to catch your legendary Pokemon in Pokemon Sapphire, save your master ball For Rayquaza...you can catch KYogre/Groudon/both with either an Ultra Ball or Timer Ball.
save it for Latias, since Latias will always run away while Rayquaza stays in battle.
After defeating him in the galactic HQ after the seventh gym, Cyrus will give you a master ball. Do not use your master ball on dialga! Instead, use it on Cresselia or another harder Pokemon to catch.
U have to catch deoxys with a timer ball or a master ball! He is lv 80. U have to catch deoxys with a timer ball or a master ball! He is lv 80.

after you see them fight you can got ot the sky pillar. to get through the sky pillar to rayquaza you need to have a master ball and a mach bike. when you get to rayquaza all you have to do now is go to him and press A. after the battle starts use a master ball to catch him. you cant use timer balls or any others cuz they dont work at all.HOPE THIS HELPS. tell me if it doesnt plz.

Yes it can because after ten turns in battle you can use a timer ball and it will mostly work without fail.
