Made a deck a bit similar to that, figured better to post here than an entirely new topic.

Plan is fractal RoL into hope, once you have hope up send in the leaf dragons and start mutating rays. If you don't get rushed down during the first few turns of setup this beats just about anything lacking mass cc or shield bypass. You can also play 2 supernovae in a turn and mutate the singularity.
It's good fun, can win surprisingly fast if you get the right mutants. It's reasonably good against all but that fastest rushes, and also in stall matchups where the opponent lacks CC, since some mutants have great breaker skills like Poison, Steal, Momentum, Growth and Dive.
