When you find it hard to catch a rare pokemon (example:Skarmory,The 3 Regis) use Whirlpool/Sand Tomb/FireSpin on it. While it's trapped,chuck Balls and you might be able to catch it easily. (That's what I think) If not, then use the same Ball in a row. Then switch out the Balls you are throwing (example Regirock 1-Ultra 2-Ultra 3 -Ultra 4-Great ) The Pkmn wont notice this and you will find it more easier to catch it.
