Trying to access CARD class variables

**So, I am making an UNO game.

I have a class called CARD that has :

using UnityEngine;
using System.Collections;


public enum KIND
{
    RED,
    BLUE,
    GREEN,
    YELLOW,
    PICK,
    DRAW4,

};


public class CARD : MonoBehaviour {
    [HideInInspector]
    public KIND COLOR;
    [HideInInspector]
    public string ID;
    [HideInInspector]
    public GameObject CARDObJECT;
    

    public CARD(KIND clr, string id, GameObject cardobject)
    {
        COLOR = clr;
        ID = id;
        CARDObJECT = cardobject;

        
}

  








}

I created all UNO cards by making a list of CARD, one example is this:

 CARD greenZero    = new CARD(KIND.GREEN, "zero", GREEN_ZERO);

I thought i was doing well untill i hit a very very frustrating wall.
When i give the player his first 5 cards i did like this:

  public void DealInitialToPlayers()
        {
            int initialCardsDeal = 5;

        for (int i = 0; i < initialCardsDeal; i++)
        {
            PlayerCards.Add(CardsBank*);*

CardsBank.RemoveAt(i);

}

for (int y = 0; y < PlayerCards.Count; y++)
{

Instantiate(PlayerCards[y].CARDObJECT,new Vector3(-2.5f+y*1.20f,-4,0),Quaternion.identity);
// Instantiate(PlayerCards[y].CARDObJECT, new Vector3(0 + y * 1.20f, 0, 0), Quaternion.identity);

}

CardsOnBoard.Add(CardsBank[0]);
CardsBank.RemoveAt(0);
Instantiate(CardsOnBoard[0].CARDObJECT, new Vector3(0 , 0, 0), Quaternion.identity);
}
this will give the player 5 cards and put one on the middle. I also initiated the cards prefabs to the screen,
My problem is, how can I access the initiated prefab’s item variables (the string ID,the enum).
For example there is now one card in the middle, how can I know its KIND(color), its ID.
It feels like i initiated the GameObject with no information from the CARD class i worked really hard to make.**

I think your problem might be that you’re using a constructor, instead of, for example, the Start() function to initialize. The unity manual says that defining your own constructor in a script component can interfere with the internal workings of unity and cause major problems: Unity - Manual: Creating and Using Scripts (See the note to experienced programmers under the Anatomy of a script file section)
