I only caught them today,it took ages
it took me like 3 to 4 hours to catch 'em. jus do one of the following:
1.get some 1 to trade u the regis from their game.then trade them bak and use reapeat ball on them
or
2.use false swipe or furry cutter on em so they have 1 hp. then try to catch em or put them to sleep or freeze them.
i recommend using timer, ultra, and repeat balls on them.hope that helped
