Few Tips From Me to Catch Pokemon Legend Without Masterball

1. try to catch the legend that at midnight, why?
    we can use the dusk ball is very effective in caves and at night.

    I was caught kyurem in a state hp 1 and status normal, only wear 5 dusk ball  (^-^)

2. before the save against the legendary pokemon first, why?
    maybe we used to play when going to sleep and the time required to capture the legendary Pokemon that is not short, so very often encountered cases fell asleep while capturing legendary pokemon.
  

If you are using Nintendo DS:
3. now try to capture Pokemon while charging your DS, why?
    continue the above case, if we fall asleep when trying to catch the legendary pokemon in the game time went on, and this means the timer ball catch rate is increasing
    I've experienced this time again against darkrai, i play at 10pm, and fell asleep. tomorrow morning I immediately tried to use the timer ball, and only with a timer ball darkrai was not slightly but HP is still orange
