I take it you mean how Azelf runs away and you have to find it in the grass?
For that case, or for any other Pokemon that run from you, there are multiple ways to catch them without a master ball.
Probably the best way is to use a move that prevents others from running away or have a Pokemon that prevents running away. After it becomes forced to battle I would use something that will paralyze/sleep/freeze the other Pokemon so it becomes easier to catch (Burn or Poison has a chance to accidentally kill the Pokemon). Then weaken the Pokemon to low health (preferably False Swipe as it always leaves 1 HP left) and throw Ultra Balls at it until it gets caught.
yes you can catch a nuz leaf in Pokemon it is at rt 213 somewhere around there, hope i helped -Boring master of time
it is not if you use a net ball twiceResponse from creator: I tried every single kind of pokeball there is in Pokemon Platinum at least five times except a master ball. Which means i tried the net ball at least five times, i still didn't catch him therefore, until there is an answer that actually works, i still think Heatran is impossible to catch and i still ask why. WHY!?
You are going to have to either use a cheat or catch it with a Master ball.
