Simic deck that is highly resistant to removal via undying, regeneration, hexproof and scavenge. Strangleroot Geist and Vorapede can end up triggering evolve twice if they do die, and then Zameck Guildmage can remove counters from them. Gyre Sage ramps to Prime Speaker Zegana/Vorapede and the extra mana can also be dumped into Zameck Guildmage or Vorel of the Hull Clade for extra counters or card draw. Renegade Krasis makes evolution twice as good. Rapid Hybridization to remove problematic creatures like Olivia Voldaren or Boros Reckoner (I ain't afraid of no 3/3!).

I'm still uncertain on the mayeboard. I feel like Give // Take really has a place in here since it has so much utility, and I also feel like Primordial Hydra or Nimbus Swimmer could work as a mana dump. Species Gorger might be a good addition at the top end as well to trigger evolve over and over.
