How to make TCG Deck (Instatiate based on Prefab)

Hello everyone! I have been trying to make the skeleton of a card game (TCG/CCG). I am having a bit of trouble wrapping my head around the deck element. So far I have a Card class which is serialized to construct all the elements of cards in the game.

Card class:

 using UnityEngine;
 using System.Collections;
 
 [System.Serializable]
 public class Card {
 
 
 
     public string cardName;
     public int cardID;
     public int cardMana;
     public int cardAttack;
     public int cardDefense;
     public int cardSpeed;
     public CardType cardType;
     public SubType cardSubType;
     public Faction cardFaction;
     public int cardGems;
     public GameObject cardPrefab;
 
     public enum CardType{
         Summon,
         Chant,
         Equipment
     }
 
     public enum SubType{
         Creature,
         Structure,
         Armor,
         Weapon
     }
 
     public enum Faction
     {
         Neutral,
         Chaos,
         Water,
         Earth,
         Wind,
     }
 
 
     public Card(string name, int id, int mana, int attack, int defense, int speed, CardType type, SubType subType,
                 Faction faction, int gems)
     {
 
         cardName = name;
         cardID = id;
         cardMana = mana;
         cardAttack = attack;
         cardDefense = defense;
         cardSpeed = speed;
         cardType = type;
         cardSubType = subType;
         cardFaction = faction;
         cardGems = gems;
         cardPrefab = Resources.Load<GameObject>("Prefabs/" + name);
 
 
     }
                        
 }

In addition to this, I have created a CardDB class which manages all of the cards in the game. I will reproduce its code here:

Card database:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class CardDB : MonoBehaviour {
 
     public List<Card> cards = new List<Card>();
 
     void Start(){
         cards.Add (new Card ("Annoyed Knight", 0, 1, 2, 2, 3, Card.CardType.Summon,
                              Card.SubType.Creature, Card.Faction.Neutral, 0));
 
         cards.Add (new Card ("Infuriated Bear", 1, 3, 5, 4, 4, Card.CardType.Summon,
                              Card.SubType.Creature, Card.Faction.Neutral, 0));
 
         cards.Add (new Card ("Ballistic Bear", 2, 4, 5, 6, 5, Card.CardType.Summon,
                              Card.SubType.Creature, Card.Faction.Neutral, 0));
     }
 }
 

I'm wondering how to add these items to list in which I can call the prefab that they reference and instatiate it when it is drawn. This is what I currently have for the deck script:

Deck:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.EventSystems;
 
 public class PlayerSummonDeck : MonoBehaviour {
 
     public List<Card> playerSummonDeck = new List<Card>();
     public CardDB database;
 
     void Start () 
       {
 
         database = GameObject.FindGameObjectWithTag ("CardDB").GetComponent<CardDB>();
         playerSummonDeck.Add (database.cards [0]);
 
     }
 
 }

Overall question: How do I make it so that when I click on the deck it draws the top card of the list, instatiates it as the prefab? Is there a way to reference the prefab attached to the card within the database?

I have created a prefab for each of the 3 cards referenced in the database. The script above sets it to load the prefab from the resources folder called Prefabs + name where "name" is the name of the card in the database. I would really appreciate some help with this! Thank you for looking and sorry about the wall of text.
