Going through your code I found a few issues:
Take a look at all the times where you access .count, it should be .count(). See lines 63 and 69.

Also make sure when you try to get the cards from the object, you reference the array it is stored. i.e. stdDeck[showMe] should be stdDeck.cards[showMe].

When you test for debug, don't forget to use double equals. Otherwise, you end up setting debug to true each time. Furthermore, if you know that debug is a boolean, you can check it like this:

if (debug) //to see if debug is true
OR!!
if (!debug) //to see if debug is false.

I have a gist coming that could help too =)
