I can't redesign your game for you but I can tell you to step back and consider the original premise of MVC.

What does your domain model consist of?

An array of card face values that represent a shuffled deck,
A score,
A list of high scores?
A count of matching attempts? (Not sure what the premise of the game is)

What does your view consist of?

A background
A deck
Some number of displayed cards
A scoreboard
Some buttons?

So the job of PureMVC is to help you get the data from the Model into the View and update the Model based on user interaction at the View.

The Card class you are torn about is probably a view component that displays certain data from the Model - specifically the face value of the card. So it must be informed of the data it is to present. A mediator would do this. When you click on the card, (perhaps to turn it over), the Mediator would listen for this event and in turn either update the Model or perhaps send a notification heard by another mediator or a command that needs to take some action, such as seeing if you clicked on the right card.

Originally implemented in Flex for a desktop-sized web browser, this port has been artfully reconceived by Brian to fit the mobile form factor, where transition into sub-screens is necessary.

Just an update on server side activity:

The PHP port currently ships with a CSS Zen Garden PureMVC-based demo.

Also the ColdFusion port has server side Hello World and Login demos.

And the Python port has an excellent Google App Engine blog demo.

This utility provides the capability for creating pipelines that pass messages between Cores in a PureMVC Haxe MultiCore-based application. Pipelines can be composed of filters, queues, splitting and merging tees, and more.

The utility was ported from AS3 by Marco Secchi.

This utility provides a simple yet effective Finite State Machine implementation, which allows the definition of discrete states, and the valid transitions to other states available from any given state, and the actions which trigger the transitions.

A mechanism is provided for defining the entire state machine in XML and having a fully populated StateMachine injected into the PureMVC app.

Standard and MultiCore versions are included.
