A timer ball? This is a hard procedure... but while u play the game, keep going to "island 2" (after beating Blaine, the fire gym leader) and talk to the person that replaced the pokemart with a stall. Most probably after you beat the Elite 4, the young man will start selling timer balls and this other kind of ball
hope i helped:)

A timer ball is good to use when you want to catch a Pokemon you've battled for a while. The more turns you have in a battle, the better more chance you have to catch to Pokemon with a timer ball. (I caught my Groudon in Emerald with a timer ball ^_^)
