Of the three games I've played with the new codex thus far, I've won two and tied one (neither had the objective, we tied on victory points). Which then went to kill points, and was also tied.
Win #1, my list was as follows:
HQ: Karandas
HQ: Farseer w/ Jetbike
Troop: Jetbike x6 w/ 2x shuriken cannon
Troop: Jetbike x3 w/ shuriken cannon
Troop: Ranger x5

Heavy Support: Wraithlord w/ 2x bright lance, flamers

Scenario: The Relic.
My opponent was playing Blood Angels. I don't remember everything he had, but I do recall he was running Mephiston, two full units of tactical marines, one of those artillery shooty tank things, one metal box on wheels, a weirdly fast predator with outflank, two units of scouts with sniper rifles, one maxed out unit of whatever the heck Spehss Mehreen assault troops are called, one unit of those cool bull#!$@ squads that can assault after deep striking, one bike with a multi-melta and a twin-linked bolter, one of those ridiculously huge fortifications with the lasturret on top, and some squad with like three or four missile launchers and one annoying small blast plasma weapon that stayed inside said fortification until I blew it up with bright lance fire and killed everyone inside. I think they were a devastator squad.
I ended up going first, so I deployed my army around my Aegis except for my scorpions which infiltrated into my enemy's backfield with Karandas. Turn one, my Scorpions all fired their shots at the lone enemy jetbike that was in their range but I only hit it once and failed to wound. It was a little depressing. Fortunately, they managed to get into cover by running after they'd fired. I then erased my enemy's big unit of assault troops from the board. Go Dark Reapers. My jetbikes expressed their displeasure with the existence of a unit of infiltrating scouts that were hiding in my backfield, and the scouts did not survive the experience. I also blew up my enemy's metal box, which he was using to block line of sight rather than to hold a squad.
On my opponent's turn 1, Mephiston decided that he didn't particularly care for the existence of one of my Ranger squads, so he murdered it in the face.
Me: "Wait, his spell does what?"
My Opponent: "Gives him wings."
Me: "... perhaps I was overly enthusiastic in the positioning of my Rangers."
My Opponent: *smirk* "Perhaps you were."
My opponent's second tactical squad also was apparently offended by the existence of my Howling Banshees, and so erased them from the board. His missile launchers and plasma gun and laser turret and snipers all flailed ineffectually against my Wraithlords and only managed a single wound, which I made my cover save for. His artillery whatever it was fired and killed two of my five Dark Reapers. My other squad of rangers was then destroyed by his other jump squad which he had chosen not to deep strike with for some reason.
Turn two, my Warp Spiders actually showed up out of reserve, deep struck, and blew the artillery thing to pieces. Then my farseer decided he'd rather be on the other side of the board and turbo-boosted to my enemy's backfield. My little jetbike squad moved up to be able to grab the relic next turn (but still out of LoS this turn). I mulched my opponent's remaining assault squad with concentrated Dark Reaper fire. After I moved my Scorpions out of cover, I needed a 9 on two dice to assault my opponent's squad of tactical marines. I managed it. Between Karandas, the Exarch (also with a scorpion's claw) and the rest of the Scorpions, we killed all but three marines.
My opponent's turn two, his Predator drove onto the board and casually flamered and then fired his twin-linked assault cannon into the backs of my Warp Spiders and murdered them all. It was depressing. Plasma small blasts killed my Dark Reapers. Then he sent Mephiston to assist his tactical squad against my Scorpions. Karandas met Mephiston in battle, and crushed Mephiston beneath his boot. Between the Exarch and the other Scorpions, all the rest of the tactical marines were also killed.
My turn 3, I took the relic and killed everything he had on the board that wasn't inside of his big fortification. Two wraithlords made short work of his Predator. My opponent's turn 3, he managed to score a single wound on one of my Wraithlords and killed two of the three jetbikes that had the relic.
My turn 4, I destroyed his tower and killed everything that was inside it, and that was the end of the game.
----------------
The tie was against Necrons, and was a brutal slog of a game on both sides that ended with neither of us having much left alive. My remaining troops at the end of the game: one swooping hawk exarch, two wraithlords, one farseer (HQ), and a Crimson Hunter. My enemy's remaining troops: a whole bunch of those little spider things (locked in combat with my farseer), one unit of immortals, two of those annoying sniper guys.
The second win was against Imperial Guard.
Against the IG, I took the following list:
HQ: Farseer w/ Jetbike
HQ: Spiritseer
Troop: Windrunner Jetbike x6 w/ 2x shuriken cannon
Troop: Windrunner Jetbike x3 w/ shuriken cannon
Troop: Wraithguard x5
Dedicated Transport: Wave Serpent w/ scatter laser, shuriken cannon
Dedicated Transport: Wave Serpent w/ scatter laser, shuriken cannon
Elite: Fire Dragon x6 w/ Exarch, fast shot
Fast Attack: Swooping Hawks x6 w/ Exarch, Sunrifle
Fast Attack: Warp Spiders x6 w/ Exarch, twin-linked gun, fast shot
Fast Attack: Crimson Hunter
Heavy Support: Wraithlord w/ 2x brightlance
Heavy Support: Wraithlord w/ 2x brightlance
Scenario: Big Guns Never Tire
My opponent took a heavily mechanized IG list. A bunch of Leman Russes. Two of those artillery barrage things in the corner. Two metal boxes full of Space Wolf allies. One IG transport with a squad of veterans inside. Two vehicles with really nasty but only 24" range guns. A Valkyrie kitted out for the murder of vehicles. A command squad hiding in the corner.
I wound up going second. That was fine with me. My opponent spent his entire first turn firing artillery barrages at me. Almost every single shot deviated off of its target and hit nothing. The dice gods were with me. An entire round's shooting amounted to two penetrating hits on a wave serpent which became glancing hits because of the wave serpent's shield.
My turn one, I advanced up the board. My minimum sized squad of bikes turbo-boosted over to out of line of sight of my enemy's guns but positioned to be able to destroy his command squad next turn. I also destroyed one of his two big artillery things with my wave serpents and then turbo-boosted my farseer and his jetbike buddies onto the craters that remained afterwards. Then I killed two Leman Russes with my wraithlords.
My enemy's turn 2, his Valk came on and killed my wave serpent. My Fire Dragons got out of it. His second artillery piece fired but missed with deviation. He fired at my other wave serpent with his Leman Russes and failed to do anything because it was in cover (OK, to be fair, he scored two penetrating hits which then became glancing hits thanks to the Serpent Shield, but I saved everything else). His IG transport moved to be able to deposit his veterans on an objective next turn. His two big scary guns fired at my wraithlords and scored a wound each.
My turn 2, my Crimson Hunter came on the board, Vector-danced, and fired all of his shots into the back armor of the Valk. Poor rolling meant I only dealt two hull points damage, but I did make it unable to turn or change flight modes, which saved my Crimson Hunter next turn because now the Valk couldn't shoot it no matter what it did. My Fire Dragons erased another Leman Russ. My Wraithguard got out of their transport and destroyed his transport. His vets hopped out. My farseer and his jetbike buddies destroyed the second artillery piece, and my other jetbike squad killed every single person in his command squad. Meanwhile, my Warp Spiders teleported onto the board and blew up one of his tanks with the scary 24" guns, and my Swooping Hawks failed to arrive because I rolled a 1.
My enemy's turn 3, he got a bunch of troops (including space wolves) onto objectives and fired ineffectually at my troops with his surviving people (and one surviving Leman Russ).
My turn 3, I killed the last Leman Russ with my Fire Dragons, killed all his veterans with my Wraithguard, killed his Valk with my Crimson Hunter, destroyed his other tank with the scary 24" gun, finally got my swooping hawks on the board, who killed most of a squad of veterans camping on objective, and then positioned myself to wipe his last remaining troops on my next turn.
My opponent's turn 4, with a mostly-dead squad of veterans, one unit of space wolves and a space wolf HQ remaining, he conceded the game.
