I love Simic Evolve, so much fun to play when it gets going. I'd suggest narrowing the creature focus. To many 2 of or 3 or which makes it inconsistent where as more 4 of and better chances to turn 1 Cloudfin Raptor turn 2 Sylvan Caryatid etc..if it were me I'd go AEtherling to sideboard for a control matchup I've learned just 1 to bring in can win the game as odd as it seems -2 Witchstalker -2 Prognostic Sphinx -1 AEtherling to sideboard -2 Fathom Mage +2 Kalonian Hydra +1 Sylvan Caryatid +2 Omenspeaker +1 Horizon Chimera +1 Experiment One give it a shot and see if the wins come more consistently

Interesting deck man i agree with the above comment to make it more consistant but aside from that it looks pretty good. +1 for simic evolve
