For healing, someone mentioned SoG are the best choice in the first page, and I agree life mark is not a good idea.
And I don't agree fractal is over power and should be nerfed.
I' ve actually tried this deck, not only in the trainer.
Honestly, the win rate of this deck to gods is much lower than standard rainbows.
Same as other fractal deck, it can't do enough damage to kill some gods but stay alive till deck out.
Anyway the fractal card bring a lot of creative ideas and generate uses of the "useless cards".
It is much better than the boring rainbow environment.
