Lots of complex evolve math. Basically demands a Verdict on turn 4 or the opponent is dead. Mana is consistent and there are multiple avenues to a win as well as resilience along the way.

This deck is designed to be a Post-Innistrad-Rotation Golgari Midrange deck that is aggressive, yet resilient to both other creatures, removal and sweepers (in the form of regenerate and some Ranger's Guile). It 'combo's' off using Gyre Sage, Corpsejack Menace, Renegade Krasis and Kalonian Hydra to put down SERIOUS threats (i.e. multiple 6/6s by turn 4).

Dream opener would be Experiment One, into Gyre Sage, into Renegade Krasis, into Corpsejack Menace which would leave you with a 7/7 Experiment One, a 6/7 Gyre Sage, a 5/4 Krasis.

From there, swing for lethal if unmolested (25 damage by turn 4: 2 on T2, 5 on T3, 18 on T4). OR just swing with Experiment and Krasis and use Gyre Sage mana to play an 8/8 Hydra that evolves everything even more...)
