Hello, HP players. My name is Joao Ricardo and I want to share some of 
my strategies with you. Here is some of them.
 
I think Transfiguration is a very interesting lesson because it helps 
you control the game. You can discard some of your opponent's precious 
cards with it, and that's my favourite deck type.
 
A very interesting card is Transfiguration Exam. If your opponent has 
lots of creatures in play you can get rid of ALL of them!! Of course you 
will discard yours too, so this card is more useful only in few/no 
creatures decks. The only problem is it's 10 lessons cost, but Hermione 
will help you in this case.
 
A card that looks like Transfiguration Exam is Table Trouble.
You can get rid of your opponent's items this way (yours too, so be careful!!)
 
Now, if you really want to blast your opponent's cards in play, you 
should play Dumbledore's Watch. "But I will blast myself too" you should 
be thinking. All you need to do is wait for the best time to play this card.
I would play this card only if I have some lessons in my hand, so I 
play the card, and the lessons in the next turn.Then I would be able to 
play more cards(Hermione is a good help). I would also play this card 
only if my opponent has lots of cards in play, or else I will lose my 
cards in play with no reason. And I have to be sure the card won't be 
discarded from play in my opponent's turn.
As a result, my opponent loses all of his cards in play. Me too, but 
it's a good idea to play healing cards after playing a Watch so I can put 
the cards discarded from play back in my deck, then I'm able to play 
them again.
 
Well, that's all for now. Bye!
