Online Trading Card Game

Need help here. What i need to do is make this multiplayer.
I am currently using photon but i have no idea how
will i apply photon here. My objective is when the game start.
My deck will be pass to the enemy deck of player 2 and vice versa.
When i place a card. My card will be placed in the enemy field of player 2 and vice versa.
Any Idea how to make this work?
Any suggestions and answers will be much appreciated. Thanks

 

If each card has an (int) id, you can describe a deck as int[].
You can send int[] via Photon or you can send individual cards. Each time you do anything with a card, send an "event". Either use RaiseEvent for that or RPCs.
