Can I emulate a callback function from jquery removeClass?

It seems that you're using CSS3 transition for doing this. The easiest way to do this is to set delay manually:

$("#card1").removeClass('flip');

setTimeout(function(){
   //wait for card1 flip to finish and then flip 2
   $("#card2").removeClass('flip');
}, 500);

setTimeout(function(){
   //wait for card2 flip to finish and then flip 3
   $("#card3").removeClass('flip');
}, 1000);

There's no built in jQuery method to check that css transition is complete.
