stack.getCard(element) doesn't exist

Hi,

I was trying to destroy a card but getCard method doesn't exist in stack.

stack = stack = gajus.Swing.Stack();
card = stack.getCard(index.target);
card.destroy();

Start by locating the Stack API and the card-destruction path referenced by stack.getCard(index.target) and card.destroy(). Check how cards are exposed and whether an equivalent lookup already exists. Done means the reported card can be retrieved for destruction, with the relevant behavior covered by an existing or new test.
