I'm creating some critical hit and critical fail decks for a 5e game I'm running. At level 1, there are 24 cards. So I made a Hit table and a Fail table. But at level 5, you at 18 more difficult cards. At level 9 you add 8 more cards. Then at level 13 you add 4 more cards. I created the 1st one [ch1]. My question: Is there a way, in the free mode, to just duplicate it and then add just the next 18 cards and make [ch2] or do I have to completely rebuild #2 from scratch with the 1st 24 cards again then add the next 18 cards?
