Delegate.CreateDelegate returns "ArgumentException: method arguments are incompatible"

Any idea what I did wrong here ? My method seems to be of the correct type

        public void RegenerateEventEnums()
        {
            FieldInfo[] fields = typeof(Card).GetFields();
            foreach (FieldInfo field in fields)
            {
                var del = Delegate.CreateDelegate(typeof(Action<Card>), GetType().GetMethod("Test"));
            }
        }

        public void Test(Card card)
        {
            Debug.Log("My card!");
        }

        public void RegenerateEventEnums()
        {
            FieldInfo[] fields = typeof(Card).GetFields();
            foreach (FieldInfo field in fields)
            {
                var del = Delegate.CreateDelegate(typeof(Action<Card>), GetType().GetMethod("Test"));
            }
        }

        public void Test(Card card)
        {
            Debug.Log("My card!");
        }

Why isn't my generic working properly ?

❔ Is there a better way to implement this "pattern"?

Hi, I'm trying to implement a pattern where I have a non-generic interface that exposes certain functions and can be used by any other class without the need for a generic, and then a generic version of the interface that helps restrict types properly when creating concrete implementations, here is an example

 internal interface IVisualElement
    {
        IEnumerable<IVisualElement> Children { get; }
        void Draw(IVisualElement parent);
    }

    internal interface IVisualElement<in T> : IVisualElement where T : IVisualElement
    {
        void DrawGeneric(T parent);
    }

    internal class ConcreteVisualElement : IVisualElement<Node>
    {
        public IEnumerable<IVisualElement> Children { get; } = new List<IVisualElement>();

        public void DrawGeneric(Node parent)
        {
            throw new System.NotImplementedException();
        }

        public void Draw(IVisualElement parent)
        {
            DrawGeneric(parent as Node);
        }
    }

 internal interface IVisualElement
    {
        IEnumerable<IVisualElement> Children { get; }
        void Draw(IVisualElement parent);
    }

    internal interface IVisualElement<in T> : IVisualElement where T : IVisualElement
    {
        void DrawGeneric(T parent);
    }

    internal class ConcreteVisualElement : IVisualElement<Node>
    {
        public IEnumerable<IVisualElement> Children { get; } = new List<IVisualElement>();

        public void DrawGeneric(Node parent)
        {
            throw new System.NotImplementedException();
        }

        public void Draw(IVisualElement parent)
        {
            DrawGeneric(parent as Node);
        }
    }

Is there a name for what I'm trying to do, and is there a better way to implement it? Thanks a lot for your help!
