Requesting data from server

Okay after working on it throughout the day I realised I was going about it the wrong way.

The way I solved it was by using the NetworkMessage class.

I did this by creating my own derivation of the MessageBase class :

 using UnityEngine.Networking;
 
 public class MessageData : MessageBase
 {
     public short id;
     public MessageData() { id = 0; }
     public MessageData(CardData data){id = data.id;}
 }

And the used this class in my client and host code to transfer the data to each other using Handlers. Here's the client side:

 private void OnMatchJoined(){
 //Other code here
  myClient = new NetworkClient();
  myClient.RegisterHandler(ZMsgType.DrawCard, OnReceiveCard);
 }
 
     public void RequestCard()
     {
         MessageData msg = new MessageData();
         myClient.Send(myMsgType.RequestCard, msg);
     }
     public void SendCardData(CardData cd)
     {
         MessageData msg = new MessageData(cd);
         myClient.Send(myMsgType.UseCard, msg);
     }
 
     private void OnReceiveCard(NetworkMessage netMsg)
     {
         MessageData msg = netMsg.ReadMessage<MessageData>();
          //Find cardData from prefab and add to hand
         CardData data = deck.deckData.cardList[msg.id-1];
         hand.AddCard(cd);
     }

And here's the Host side:

 public void OnMatchCreate(bool success, string extendedInfo, MatchInfo matchInfo)
     {
 //Other code here
             NetworkServer.RegisterHandler(myMsgType.RequestCard, OnRequestCard);
             NetworkServer.RegisterHandler(myMsgType.UseCard, OnSentCardData);
 }
 
     private void OnRequestCard(NetworkMessage netMsg)
     {
         CardData data = deck.DrawCard();
         MessageData msg = new MessageData(data);
         NetworkServer.SendToClient(netMsg.conn.connectionId, myMsgType.DrawCard, msg);
     }
 
     private void OnSentCardData(NetworkMessage netMsg)
     {
         //Game Logic here
     }
