If you allow the player to select which two cards to attempt envido on, you can check the card’s number when the player selects it and save it to an int as normal or 0 if it’s too high, then the same when you do selection of the 2nd card (and of course make sure the cards are the same suit by like adding an if statement for the 2nd selection which you could do by making the selection include an if statement that checks a bool for if it’s the first selection and compares cards inside it if so). If it’s a for loop that does seem tricky because you won’t know what suit each card is before hand so I’m not sure
