I've been experimenting lately with the water deck, and I have to say it might just be my new favorite.
So I rented Lobstradamus and Coral wraith for pretty fair prices, using the Lobstradamus as the tank in most battles, and then Corral wraith 3rd or 3th position. This build is overpowered in low mana matches against most other builds in bronze levels.
Here's an example of some battles if anyone's curious:

But yeah, if anyone's been feeling discouraged losing a lot lately, sometimes all it takes is changing things up!
