You could compare them to a limited edition 1 ever made Legendary Pokemon that you have to win 1st place in a wi-fi tournament hosted by Nintendo to even have a CHANCE to catch it and that it has a low catch rate where as you would either need a Master ball, or use false swipe, paralyze it, make it sleep, and throw at least 99 shadow balls after 7 PM to up the catch rate effect of the shadow ball.
Oh my god why won't my shadow balls work on this Vietnamese pokemon?!
