Random spawnpoint where only one prefab can spawn!

Question

So I'm creating this cardgame where the cards spawn to a circle. The card should be always in random order in the circle, but when I try to make a random spawnpoint most of the cards only spawn to one or two of them. I have 52 spawnpoints where the cards should spawn but I just can't figure out how to make this work :( Here's the code:

 using UnityEngine;
 using System.Collections;
 
 public class Begin : MonoBehaviour {
     //Hertat
     public Transform H1;
     public Transform H2;
     public Transform H3;
     public Transform H4;
     public Transform H5;
     public Transform H6;
     public Transform H7;
     public Transform H8;
     public Transform H9;
     public Transform H10;
     public Transform H11;
     public Transform H12;
     public Transform H13;
     //Ruudut
     public Transform R1;
     public Transform R2;

Whenever you have objects in a list/array and want to do something to each of them once but in random order, the easiest way to go is to make a List and remove each item after you have dealt with it.

     using System.Collections.Generic;
     ...
     void Spawn ()
     {
         // array of all cards that must be spawned
         Transform[] allCards = new Transform[]{
             H1,H2,H3,H4,H5,H6,H7,H8,H9,H10,H11,H12,H13,
             R1,R2,R3,R4,R5,R6,R7,R8,R9,R10,R11,R12,R13,
             C1,C2,C3,C4,C5,C6,C7,C8,C9,C10,C11,C12,C13,
             P1,P2,P3,P4,P5,P6,P7,P8,P9,P10,P11,P12,P13
         };
 
         List<GameObject> allSpawnPoints = 
             new List<GameObject>(GameObject.FindGameObjectsWithTag("Spawn"));
 
         // check there are equal amount of spawns and cards
         if (allSpawnPoints.Count != allCards.Length)
             throw new System.Exception(allSpawnPoints.Count + " spawnpoints found and "+allCards.Length+" cards found. Mismatch!! Can't proceed");
 
         foreach (Transform card in allCards)
         {
             // pick a random spawnpoint
             int spawnIndex     = Random.Range(0, allSpawnPoints.Count);
 
             // instantiate a card there
             Instantiate(card, 
                     allSpawnPoints[spawnIndex].transform.position,
                     allSpawnPoints[spawnIndex].transform.rotation);
 
             // remove the used spawnpoint from the list
             allSpawnPoints.RemoveAt(spawnIndex);
         }
     }
