You can use any PokeBall, but you will have a better chance at capturing it if you use stronger PokeBalls, like the Ultra Ball. You can also use the Timer Ball if the battle is lasting a long time.
Use this gameshark cheat code Deoxys 8C5DE8C8A33E9D88 or C5946A0E65BE02B0 or FBC061A9072FC320
I have no Idea about it on Ruby But I do know its on emerald. But My brother was talking about Deoxys on Ruby so Its a 50/50
yes but not as a playable character it comes out of a pokeball
I recommend the master ball
throw a pokeball at it
no trade it from emerald ruby or Sapphire
With a Pokeball.

There's no way to catch Deoxys in Ruby or Sapphire in the wild unless you use a GameShark or an Action Replay to make it appear in the wild. Deoxys can only be caught via Nintendo events which have since passed. Now it's only available if you know someone who can trade you one.
Got Deoxys and trying to figure out what form I should use. Does it depend on my playstyle or is one form better than the others?
with a pokeball
You can't.
