I played two games this weekend against a Tier 4 Nemo list.
Swordknights + UA
I was using my 35 point Butcher list.
The first game, not knowing much about Nemo, I had my three heavies in a line close together to screen Butcher. Nemo arced Voltaic Snare onto the middle one and managed to pin down all three in a bottleneck. The game was over at this point because I couldn't stop Nemo from doing that every turn and he was free to mop up the rest of my army.
The second game went better (although I still lost). I spread the 'jacks out more and put early pressure on the Lancer, keeping it back from my lines. He tried to kill Butcher with the Thunderhead but didn't do much. On my turn I feated and wrecked a fully health Thunderhead with Arcane Shield on it using just the Great Bears - awesome!
The game then turned into a big melee as we ground each other's armies to death. Butcher used Obliteration a few times to kill 5 or 6 Stormblades, a Kodiak vented steam and took out another 4, while I eventually lost the Kodiak, Spriggan, and Great Bears.
The game came down to Nemo, Lancer, Squire, and one Stormsmith against Butcher and a Kodiak. The Lancer and Nemo's gun whittled down the Kodiak while Butcher got tripped up on all of the wreck markers on the field. The Lancer killed my Kodiak and in response Butcher cast Obliteration on Nemo, leaving him with two boxes left. I didn't get a second chance though because the Lancer and Nemo's gun killed Butcher.
