Deserialize nested xml

I have an xml document for my game which contains a number of decks which are populated with specific cards. My xml file looks like this:

 <?xml version="1.0" encoding="utf-8" ?>
 <CardCollection>
   <Cards>
     <Deck DeckId="1">
       <Card Id="1">
         <CardElement1></CardElement1>
         <CardElement2></CardElement2>
       </Card>
       <Card Id="2">
         <CardElement1></CardElement1>
         <CardElement2></CardElement2>
       </Card>
       <Card Id="3">
         <CardElement1></CardElement1>
         <CardElement2></CardElement2>
       </Card>
     </Deck>
     <Deck DeckId="2">
       <Card Id="1">
         <CardElement1></CardElement1>
         <CardElement2></CardElement2>
       </Card>
     </Deck>
   </Cards>  
 </CardCollection>

I have a class Card.cs which looks like the following:

 using System.Xml.Serialization;
 
 public class Card {
 
     [XmlAttribute("Id")]
     public int id;
 
     [XmlElement("CardElement1")]
     public string cardElement1;
 
     [XmlElement("CardElement2")]
     public string cardElement2; 
 }

And a class Deck.cs :

using System.Xml.Serialization;

 public class Card {
 
     [XmlAttribute("DeckId")]
     public int deckId;
 
     [XmlArray("Card")]
     public Card[] cards;
 }

I'm using a class called CardContainer to populate a List decks with this information:

 using System.Collections.Generic;
 using System.Xml.Serialization;
 using System.IO;
 using UnityEngine;
 
 [XmlRoot("CardCollection")]
 public class CardContainer {
 
     [XmlArray("Cards")]
     [XmlArrayItem("Deck")]
     public List<Deck> decks = new List<Deck>();
 
     public static CardContainer Load(string path)
     {
         TextAsset xml = Resources.Load<TextAsset>(path);
 
         XmlSerializer serializer = new XmlSerializer(typeof(CardContainer));
 
         StringReader reader = new StringReader(xml.text);
 
         CardContainer cards = serializer.Deserialize(reader) as CardContainer;
 
         reader.Close();
 
         return cards;
     }
 
 }

I can get hold of the Id's of the decks using this snippet of code:

 CardContainer cardContainer = CardContainer.Load(path);
 foreach(Deck deck in cardContainer.decks){
        Debug.Log(deck.deckId);
 }

However I have no idea how to populate the Card-array in Deck with the cards belonging to each deck. Is there anyone who know how to do this?
