I'm back again with three cards.  This is another annoying strategy of mine :D First you play  Diagon Alley when they have a lot of cards in their hands.  Then you play Charms Exam oh and make sure you have 2 or more Charms Exams in your hand.  If they draw 5 or more play another one just to be safe.  On the next turn play confundus to take away his hand and play some spells or something.  Then when he solves play another Charms Exam if he draws 5 or more and that's it.  This is another one of my annoying hand strategy.  :D
