Better way of doing what i just did (dont know how to call it)

I have this method that removes sewing cards from my EF context. Basicaly i have a main SewingCard class and around 15 classes that derive from SewingCard. All of those classes have their own DbSets. I want this method to accept a parameter which is a list of mixed types of SewingCard derivatives. So when i write this function i dont really know what type of sewing card will be removed, except that its a sewing card. I thought of using reflection and i did it and it works. You can see the code below. But i think some things could be done better. For example im doing

var removeMethod = dbSet.GetType().GetMethod("Remove");
removeMethod.Invoke(dbSet, new[] { sewingCard });

but i would want to do it like this

dbSet.Remove(sewingCard)

Below is my current code of that method

    public void RemoveSewingCards(List<SewingCard> sewingCards, ApplicationDbContext context)
    {
        //getting the properties of context which holds SewingCards
        var dbSets = context.GetType().GetProperties()
            .Where(p => Attribute.IsDefined(p, typeof(IncludeSewingCards))).ToList();

        //iterating through sewingCards list
        foreach (var sewingCard in sewingCards)
        {               
            var sewingCardType = sewingCard.GetType();
            // getting the correct dbSet for the correct sewingCard
            var dbSet = dbSets.FirstOrDefault(d => d.PropertyType.GetGenericArguments()
                    .Any(a => a == sewingCardType))
                .GetValue(context);
            //getting the Remove method of dbSet
            var removeMethod = dbSet.GetType().GetMethod("Remove");
            //calling the method
            removeMethod.Invoke(dbSet, new[] { sewingCard });
        }
    }

I was trying to pass dbSet as IDbSet<dynamic> but that doesnt seem to work for me. I was probably doing something wrong. the dbSet ends up being null when i try to cast it.
