The best way to screen a carnosaur is with a bigger carnosaur. As long as you remember to screen that carnosaur with a bigger carnosaur too. And so on. Eventually the cannon causing you problems is in combat with a giant carnosaur and you have around 12 carnosaurs left over to mop up his army. Duh. PS. This is an awesome thread. I fricken love skroxigor from a thematic point, and the handbook says they are ordinary. So I'm thinking I take a carnosaur to justify the skroxigor. Talk about win/win.
