Sure I'd love to see your build sometime! I thought about adding
Experiment One to the list, but liked the value of
Simic Charm over it as it gives a little more flexibility to answer a situation where you would need a regenerating creature by buffing in combat, hexproof to counter removal, and bounce for whatever. I see the value of theoretically infinite regenerates on
Experiment One, so i could see it as a very strong sideboard card in many matchups. I hadn't thought of
Avatar of the Resolute that sounds like a really great card for any Simic Evolution list. Usually mana isn't a problem as
Gyre Sage generates ridiculous amounts of mana and even if i don't find one the combination of CMC 3 or lower (except for
sky swallower/prime speaker) and Simic Growth Chambers keeps the deck fairly solid on mana.
