what is please the most efficient way to delete a slice from the start of a longer array (after I have copied it to another array)?

Do I really have to copy a large slice of the array to itself, like in the last line here:

        pile_array := pile_array || swap_array;

        /* here I copy away swap_len elements */
        new_hand := pile_array[1:swap_len];

        /* here I don't know how to efficiently remove already copied elements */
        pile_array := pile_array[(swap_len + 1):ARRAY_LENGTH(pile_array, 1)];

or is there a better way?

This looks like something for card hands?

What you are doing seems correct to me.
