Condorcet methodology
Hi, This is a problem of voting, as it, we need to find theoretical results to solve this. It is a multi-winner vs single-winner problem. We want a single-winner solution, for this, we can use one of the approaches that are aligned with the Condorcet methodology. We rank the 3 cards, 1 the first, 3 the last, and for all the others we select a number greater than 3. After that, we know that if we sum, the result can multiply, but if we applied the order of election of each individual, and see the order of each cards. But, we can be in the Condorcet paradox, then we do have not a Condorcet winner (absolute winner) then as a final solution and the solution to our problem we can use Kemeny young method to solve this problem, where the no choose cards are with the all with the same rank. Regards, Francisco.
