gets you all spells of any BRB
lore OR the Tizz lore. FWIW
being able to take all the Tizz spells makes the lore much better
On the rest of the list, I'm no demons expert, but 2 things I notice ...
1) No BSB
with the Banner of Screw <insert lore here>? Good on you, but a bit surprised to see not even one spellbreaker to make up for it. Though the Scribes won't mind if your opponent gets stuff off
2) My recommendation for the Tizz herald on disc is to put him on a flying chariot, something like:
Herald of Tizz - master of sorcery, spellbreaker, chariot
I think that works out as far as gift allowance goes, and it's also one of the units I've seen taken over and over again. Very versatile, US5, flying, impacts when you need them, etc.
If you need points I see many places to get them from, like a screamer or the pyrocaster, and so on. Interesting list otherwise, much different from what I've seen kicking around the fora.
