thanks! honestly, I think I spent too much time looking at artworks just to make those mock-up cards and it's good that it seems to be worth the effort. :)
I appreciate that the balance team didn't rush into pushing out sleep 2.0. As you suggested, there will be some ways to take advantage of being able to damage your own creature (I must admit that being able to hit your own Hydra is quite creative and could have been really fun or annoying if you're on the other side of the board).
