Trigger Card Drawing/Card Deck

Hey guys I am trying to get a basic trigger down for drawing from a card.

Atm each time a player uses the "Card Draw" ability, aslong as they have Draw Points (Lumber) they can draw a card.

I have a Rnd Integer that randomly picks a number between 1-60 (60 cards in deck), I also have a boolean checking if each card has been drawn before.

The problem is I do not know how to go about this, I have tried doing a Loop checking each Integer A 1-60 if the card has been drawn before, however I do not know how to make the loop run again if the card has been drawn before.

Can anyone help, there must be a simple way to do this, I basically just want a trigger picking a random card, if the card has been drawn before, it reruns the trigger until a card that hasn't been drawn before is drawn.

To facilitate "real" card drawing without shuffling, you would need a linked list to make things easier.
However, considering you only need a "random" card every time, I think the below is the best way to do it:

1. Get i as a random number from 1 to [deck size]
2. Draw ith card
3. Put [deck size]th card to ith slot
4. Decrement the total size of the deck by 1

Do you code in GUI or (v)Jass?
