I like the first one a little bit better in terms of creature selection, but I like the enchantment selection a little bit better in the second book, though it would be too much for the 1st book.
Overall, there are a few suggestions I have:
Eagleclaw Boots are good, but I would actually stick with Leather Boots for a Priestess with Veteran's Belt.
Similarly, I would consider running a Rhino Hide as another source of armor for your mage.
I would run a Bear Strength for Brogan in the first list.
For the first list in particular, I don't think you need that many Nullifies. You aren't relying on a single massive threat, you're playing multiple threats, which means that Nullify shouldn't be that important for you. Having 1 or 2 is probably enough, and I think you could get away without any. For the second list Nullify makes a bit more sense, since you are building up just a few creatures to be huge monsters, and losing an action with one of those creatures is a much bigger deal.
In the second list, I would consider Lay Hands.
What were you thinking in terms of the opening? Something like:
Turn 1 (20): Asyran Cleric -> Battle Forge (7)
Turn 2 (17): D Meditation Amulet -> Meditate -> Temple of Asyra -> Mana on Temple (7) [1]
Turn 3 (17) [2]: D Enchanter's Ring -> D Guardian Angel -> Meditate -> FD Rhino Hide -> Mana on Temple (
[1]
Puts you in a pretty strong position and is reasonably flexible in the face of aggression. It's pretty similar to my Anvil Throne Warlord opening. You can substitute another creature for round 3. Brogan gives you a strong offensive threat, another Asyran Cleric gives you an even stronger economy, and Guardian Angel is a strong defensive play. If you are worried about a strong attack in round 2, such as double Hurl Boulder, you can just deploy Dragonscale Hauberk and play the Temple of Asyra or Guardian Angel, depending on how worried you are about aggression. You'll be a little behind in economy, but something like that puts you in a much stronger position against a fast attack.
