It's not a method, it's just your luck. There is no such system to the card you get from NPCs.

Main point is you have a better chance to get cards you don't have by challenging NPC's then wasting MGP on packs on repetition based on theme and not likely to get the ones your missing.
You realize those packs have cards you can't get from anywhere else, right?
