That's only if you're ChrisG. I'm saying this since I run a Morrigan similar to his (I've got a long way to go before I can say mine is like his), and like ChrisG zero is an issue for me. He gets perfected by lightning loops, and I don't blame him. My best friend / greatest rival has a flawless zero team. Plus doom works best with viper/Strider.
