Some of the cards I had also will lose their price significantly but it's okay I guess.

It seems to me that they are trying to push a more control meta because most of the changes were bad for aggro cards and good for some control ones. Metamorphosis is one I am most sad about since I play magic. As for control deception its still as good as it is now I guess and maybe a bit better with a slower meta. Also they said the next changes will touch Anubians so even better for control decks!
