Here is a little deck I'm playing with against AI3/Bronze/Silver:

6u3 6u3 6u3 6u3 6u3 6u3 6u7 6ve 6ve 6ve 6ve 6ve 6ve 71a 745 745 745 745 77g 7ap 7ap 7dm 7gn 7k6 7n0 7qb 7qb 7t9 80h 80h 8pl
I'm afraid it's a little slow sometimes to dominate silver league but it's fun to play.
Maybe this kind of strategy would be more powerful in a duo Life/Gravity (adding some ephemerine etc) but I like the idea of an eternal mitosed charger in my game.
Deck Helper comment: The deck below was posted before the 1.32 game update and as a result may work very differently now. Use at your own risk.
Edit: It seems something like that is quite more efficient:

6qq 6qq 6qq 6qq 6qq 6qq 6u0 6u3 6u3 6u3 6u3 6u3 6u3 71b 745 745 745 7ap 7ap 7ap 7q3 7q9 7q9 7q9 7qu 7qu 7qu 80h 80h 80h 8pj
Still needs some changes I think.
