In my opinion,it's not how you catch the card,but how you shot your card.If you can control the speed,the card flying track(some times it just seems too high or too low for your right hand to catch),then you can catch them easily.I spent a year to get this move down.
And a suggestion is make your right hand far from your left hand(at least more than half a metre,then focus on your left hand),then you are not let your right hand catch the card,but to aim at your right hand.
