A lot of people are comparing the ‘Evolve’ mechanic to the old ‘Graft’ one that the Simic Guild had last Ravnica Block. I think that Evolve is slightly better though.
The regenerate ability is good if you overcommit and you’ll be able to somewhat rebuild instead of just outright losing everything. it gets better if your Turn 2 is a Strangleroot Geist (that way you get even better post Supreme Verdict recovery).
No fear! well, kind of….
