Terminus as a Front Line Caster: Army Lists

I've already posted one 35 point list in my previous posts. I'm hanging out with a friend tonight and we are going to play some lower points games so I thought I would tackle the list building portion of my homework. I'm supposed to be building lists keeping the following in mind:

1. List will include troop options to block avenues of attack to the warcaster.
2. List will include models with abilities that deny enemy models their ability to move or act.
   
3. List will include models with abilities that promote focus efficiency. (See my article on Cryx and focus efficiency).

We'll start with a 15 point list:

• Terminus - Of course
• Deathjack - This guy is the king of focus efficiency and deadliness. His only downside is that he tends to steal souls that could otherwise go to Terminus. If I owned a Seether model I would switch Deathjack out for that and add a Pistol Wraith to increase my ability to freeze models.
  
• 6 Bane Thralls - I love these guys, and they do a good job serving as Terminus' escort.
  
• Warwitch Siren - Not super effective at this points level since she won't be putting focus on deathjack, but her venom attack can come in handy and her shadow bind ability has a good chance to root an opposing warjack/beast for a turn.

For 25 points I would add to the above:

• Slayer - Open hands let the slayer lock the weapon systems of opposing jacks. The Warwitch will give this guy the single point of focus he needs in a turn.
• Pistol Wraith - Chain Attack: Death Chill roots opposing models and POW:12 shots are a big threat to opposing infantry and solos.

The 25 point list is actually one point under, so you could swap the Bane Thralls for Bane Knights. The knights are more maneuverable thanks to ghostly, but you give up the debuff aura that the thralls provide.
