I've taken the plunge and despite what I said, I have signed up to a tournament. But it is a 500 points tournament and follows the "Sieze the Tower" restrictions, so less inclination towards abuse.

I have come up with these two lists, which one seems better?

As well, I can also take an Aspiring Champion on a steed and lance instead, but unfortunately I would want to use my Chaos Character on the big dog, but sadly his base is too big...
