IIRC, I think that "Lord of Tzeentch" is actually a Lord of Change, which
FoC switches Daemon Princes of Tzeentch from
HQ to heavy support, thus making the list legal.
Its all fun and games until you stare down the barrel of 9 broadsides
The list looks like fun, but I feel like it will either Win HUGE, or lose HUGE. With very little inbetween. I mean you've got very little troops, and what do you do if they die?
