Too be honest I agree with Sebenkos first idea of using Mines. Even due they still halve their AD, using 3 Ptolemy's to block off it's path really works. I used it once with a pretty good effect. The Ptolemy's move forward in Stratospheric height. When they are close by, drop them to obscured and drop your mines in his path. The total linked AD will be 14AD, halfed will be 7AD with High Payload. Meaning you still score and average of 8 hits resulting in a critical. Keep the Ptolemy's in his area to keep dropping mines. If he is evading the mines, use Frigates or Corvettes of your own to detonate them. It is expansive but if your really want it dead then just do it! Otherwise just ignore it, out manoeuvre it, use Orbs to keep it contained. I sometimes use the Alpha orb to block it's paths with portals. Place one portal in his pathway and the other one in an island. Then he must change course and use the Dilation Field on him to half HIS AD on attacks. You can also use the Dilation Field to have a good boarding chance. Deal some damage to reduce AA, use the Dilation field to half his AA in additional and then just board with Corvettes or High AP models. Yes you will lose probably due to Security Posts 4 and 5 AP BUT you will deal some damage and if you keep assaulting him with AP he will collapse. Assuming that he will have between 1-3 AA when boarding you will lose 2 AP from the 10 Corvettes. 8 will land and you will score an average of 6-8 hits. Meaning that 2-4 AP die from on the Terror Ship. Do this again with another corvette squadron or Zenos (as Zenos can also be used good in short range) and you will have it, prize the model for more points and from this point his Phase Generator is down (if not mistaking due to the successful board). You will have additional points and if your opponent is steadfast on retaking the terror ship you just blast it apart before he can even re-board it. That is what I do with it.
