How to change 10 cards to jack queen and king

I am making a blackjack game that involves 2 decks. I need to assign the number one cards to Ace's and the 10's to jacks, queens and kings.

my code:

%Making the deck of cards

cardValues = [1:13, 1:13, 1:13, 1:13,1:13, 1:13, 1:13, 1:13];

cardValues(cardValues>10) = 10;

if cardValues >= 10

cardValues = 10;

end

deck = [cardValues];

deck=deck(randperm(length(deck))); %this shuffles the cards
