The deck is focusing on counters, via evolve and such. I just made it out of whatever I felt like, so there's gonna be some Gatecrash and Return to Ravnica amongst others.
The gist is getting some Experiment One's out, and some other creatures. Then, when you get for example a Wall of Blossoms out, you can keep returning it to your hand via Roaring Primadox, while giving it trample with Crowned Ceratok. There's some non-evolve counter items as well, letting all the ones that does not get evolve counters get some counters as well. Combine Madcap Skills with Alpha Authority to give +3/+0 unblockable hexproof cheaply.
