Another try. List don't remove properly

Question

I hve that script:

public void ActivateCard(Card card)
        {
            Debug.Log("Activating card: " + card.CardsData);
            if (card.CardsData.creatureName != string.Empty)
                Summon(card);
            else
                CastSpell(card);

            if (_hand.Cards.Contains(card))
            {
                _hand.Cards.Remove(card);
                Debug.Log("Card " + card.CardsData.cardName + " deleted");
                Debug.Log("now we have(cards): " + _hand.Cards.Count);
            }
                

            _hand.TakingCards(0);
        }

And I expect that card will be removed from the list. But it allways remove only FIRST element in there. Here's what I have(card can't be the same in one list):

ADDICTION:

It's not a full code, but it's all we need I think. Here's how this method calls: -I-

public class InputClass
{
  void Update
  {
    if (targetSet)
     {
         if (Input.touches[0].phase == TouchPhase.Ended)
                    Cancel(true);
     }
  }

  void Cancel(bool isDone){ _actCard.Cancel(isDone); }
}

-II-

class ActCard
{
  public void Cancel(bool isDone)
  {
    if (isDone)
     {
        _activator.ActivateCard(_card);
     }
  }
}

-III-

class CardActivator
{
  public void ActivateCard(Card card)
        {
            Debug.Log("Activating card: " + card.CardsData);
            if (card.CardsData.creatureName != string.Empty)
                Summon(card);
            else
                CastSpell(card);

            if (_hand.Cards.Contains(card))
            {
                _hand.Cards.Remove(card);
                Debug.Log("Card " + card.CardsData.cardName + " deleted");
                Debug.Log("now we have(cards): " + _hand.Cards.Count);
            }
        }
}

-IV-

public class Hand
{
  List<Card> _hand = new List<Card>();
  
  public List<Card> Cards
        {
            get { return _hand; }
            set { _hand = value; }
        }
}
```

Basically contains does not know how to identify the correct card in your list since you didn't implement those. You can take a look at this stackoverflow.com/questions/2629124/… Your equals should return something that is unique for all your cards, like an id, name or a combination.
