Assuming that you have a 1 AS 2 DS ratio, each 5* card will cost roughly 6 AS 12 DS. Each time you attack you will use half the the AS and DS you got. So the number of 5* card that you can field right now can be calculated by the [b]lessor[/b] of these 2 amounts:

((Current AS)/6)/2=Current AS/12

and

((Current DS)/12)/2=Current DS/24

Let's say you want to field 3 5* cards. And currently you only have 12 AS. How long do you have to wait? Well as shown you will need 36 AS (36/12=3). Since AS regens at 1 per minute, you will need to wait (36-12)/1=24 minutes

Same situation as above, let's say you only have 48 DS. Well as shown you will need 72 DS (72/24=3). Since DS regens at 2 per minute, you will need to wait (72-48)/2=12 minutes.
