Dynamically adding and removing cards from the stack

I've got the cards working perfectly in a prototype Meteor.js app, and I'm trying to add and remove elements from the stack. I haven't spent too much time trying, but I thought it might make a good example. Thanks again!

The issue mentions a prototype Meteor.js app and the card stack, but no repository file, test, or entry point. First locate the stack API and determine how cards are currently represented; clarify the expected add/remove behavior before implementing and verifying that both operations preserve normal stack behavior.
