How do you use your tantalus?

I have a local tourney coming up in April that I am thinking of building and painting my tantalus (that has been sitting in a box for an age). How do you all use yours, what do you run inside it etc? Also any advice on how I should use mine (within the limitations of the list below). Thinking of running it with trueborn, Archon and Grots inside

It would be a nice 7th edition list. Not a very good 8th one. Talos are horrible. Grotesques not worth it anymore. Wyches are discutable, but a single unit won't hurt your list too much. The rest is ok.

Also, you dedicate points to beastmaster, but the number of beasts is rather low. Maybe have more, or use the aura of your tantalus to boost your beast's leadership.
