Have an array (or even a string) and add to it whenever you select a card. That way whenever you select the second or third card you can select another one if it is in the array (or string).

Here is one way to do it… I didn’t check if it works.

String pickedCards = ""
int totalPickedCards = 0
boolean continue = true;
for(continue) 
{
  tempVariable = pickedCard
  if (pickedCard.contains("/"+tempVariable+"/") == false) { // if you didn't already pick it then
    pickedCards = pickedCards + "/" + tempVariable + "/";
    // save the card you picked - stored in tempVariable
    ++totalPickedCards
  }
  if (totalPickedCards >= 3) { // exit loop if you have 3 cards picked
    continue = false;
  }
}
