For PVP2, you'll need some form of control. From experience, I've found that anything but an Immorush, usually isn't fast enough to set up before a deck with control takes you down. Consider taking out the Puffer Fish as they aren't the greatest for quick kills, bad cost to damage ratio until late game. Perhaps +3 Arctic Squid, +2 Permafrost Shield, +1 Pendulum, -6 Puffer Fish.
