Well, looks like no one is writing new tips on the last days...
does anybody know why? I don't.
 
So here is one.
 
Transfiguration decks count on a very cool card with 2 little weak 
points. I'm talking about Mirror of Erised (as you have already been noticed 
in this tip title :-p). It is a Gringotts' Vault Key for 
transfiguration, but a little more powerful. It lets you discard your hand for 
searching your deck for that much number of cards. It can combo with a 
not-very-used card which is called Harry Potter(which increase your 
card-drawing ability)! If you buy a few cards, use the mirror to search your 
deck for better cards. Just be careful not to draw a high number of cards 
unless you want a quick loss.
 
After using the mirror your hand will be discarded. Then it's time to 
play a few healing cards to put your hand cards back in your deck (then 
you will not lose your hand cards after all). Some of these healing 
cards should be taken from your deck as you use the mirror. You should 
also take lessons and use Hermione to play them, then take damage cards 
and hurt your opponent a little.
 
I said that the mirror has 2 weak points: one is your hand that gets 
discarded. The other is the 10-power-cost which is a little nasty, but 
items (and lessons, of course) solve this problem.
 
Thank you and so long.
