Dealing with large number of triggers/varriables and states - Using Cards

The biggest problem is keeping track of which cards have been used, unless you want to always follow the same order. If you want to use a random order, without repeating any cards until they have all been used, there is no way SL can do that. So you need to use JS. I would create an array and sort all the cards into it randomly. You would need either to delete each card from the array as it is chosen, or use a variable in SL to keep track of where you are in the array. I would execute the JS every time I wanted a new card and have it  change a variable in SL to match the chosen card ( 1-52). The card pile would have 52 states, and every time the variable changed, a series of triggers would change the state of the pile to match the variable number.

You can use text fields in Storyline as arrays... Here is an old sample of mine showing how you can setup a textfield in Storyline to act as an array.

When you showed some element of the array, its easy to remove with this code..so it never will show again.

var array = [1,2,3,4,5,6,7,8,9,0];

function arrayRemove(arr, value) { 
    
        return arr.filter(function(ele){ 
            return ele != value; 
        });
    }
    
    var result = arrayRemove(array, 6);
    // result = [1, 2, 3, 4, 5, 7, 8, 9, 0]
