There have been alot of educated solutions and i know that mine isnt better but i came up that the Creators could use the faint, attempt,faint, attempt,etc. for only really rare but it would still be extremly hard to catch using this and/or only for legendaries because pointed out by Jerry that well all used save and then try again if we run out of pokeballs or the legendary faints so we could only have it in place for the Legendaries.... Sorry if in other forums it says anything about Legendaries arn't availble for capture.

yay i just joined and i will waits foreva cuz i have a life and i can do stuff in my spare time....
