No
You can buy timer balls at Canalave city and at the Pokemon League.
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.
Well to get Garitina use the master ball to catch Garitina or some dusks balls or timer balls or some quick balls.
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 ^_^)
well the most rarest pokemon i would say is unixe azelf and mespirt they suck i know but there the rarest in the game and dialga and girantina are rare to but not as rare as mespirt, azelf and unixe.
You can buy them, at the Pokemon leuge thjey have evry kind of ball except master and cherish balls
Timer balls can be found in the Pokemart in Rustboro City
first get six pokemons then have about 4 or 5 timer balls and 4 ultra balls no master ball then take a lot of time and turns when palkia has red life so use our ultra balls then when u have 1 Pokemon left use some timer balls if your Pokemon is strong if not when ur second Pokemon use those timer balls i got palkia without the master ball.... hope it works it works for me
You can buy them at the Pokemon mart at the Pokemon league. I buy my timer balls, heal balls, etc. at the Pokemon mart in canalave city
Well, get a lot of ultra and timer balls. Bring a Pokemon who can paralyze or put him to sleep
Grand Master Greevill has shadow zapdos to catch it weaken it to red hp then paralyze it use many ultra balls when your running out try timer balls i caught it with a timer ball.
You could get timer balls by buying them from the store at the Pokemon legaue or helping the man for the newspaper in solceon town.
Timer balls are only in Pearl and Diamond
Timer balls are pokeballs but are more effective the longer the battle has been going.
at cinnabar island there is a net ball 5 master balls in the hidden chamber (you need hidden power) and last but not least 5 timer balls!not sure but I think after you beat the league Kirt will use two different apricorns
Once you help the Devon corp you can purchase timer balls and repeat balls at the rustboro city pokemart.
Go back to the sky pilar with your mach bike and get to rayquaza and use Timer, Ultra, and Master balls.
