How to assign a Variable with a Raycast

So in my script I am using Raycast to identify an object when clicked. So far it detects objects with a tag of "Card" (I have some more code in it but it doesn't affect it yet) what I want it to do is to assign said object as a variable called Card for later use.

Here's the code:

 #pragma strict 
 var Tile : GameObject;
 var Check : boolean = false;
 var Card : GameObject;
 
 function Update(){
 
 if(Input.GetMouseButton(0)){
 
 
 
 var hit : RaycastHit;
 var ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     if(Physics.Raycast(ray,hit)){
         if(hit.collider.tag == "Card"){
             Debug.Log(hit.collider.name);
             Check = true;
             Card == Object;
             }
         }
     }

Now how can I use the Raycast to take an object Tagged "Card" and assign that GameObject to the Var Card.
