Magma Golem is a cool option for an Adramelech Warlock that should work well with fire immune demons and strong position control. Whether it will be worth the effort is hard to say, but I'd like to give it a try once it's released.
Messenger of Bim-Shalla makes Temple of Asyra more attractive, particularly if holy gets a more spellbook efficient way to boost swarm (Rust and Acid Ball are nice, but Marked for Death is kind of pricey for a holy mage).
I'm not really interested in Unstable Fire Imp. I can see someone including him in a Pentagram build, but I probably wouldn't bother.
I like that Reinforce allows you to keep your conjurations alive. For spawnpoint builds it could be worthwhile.
I like Life Link because it strengthens board dominance plays, and gives holy mages the ability to heal a creature over time.
Hidden Tunnels will be an interesting way to improve mobility for the warlord.
I really like the look of Dwarf Kriegshammer. It will make a dwarf focused build much more worthwhile. I would much rather use Dwarf Kriegshammer than Dwarf Kriegsbiel.
Bind Spirit is pretty narrow, and I have trouble seeing why anyone would include it. Holy mages can generally kill incorporeal targets pretty efficiently, and it's not that spellbook efficient for anyone else. Other solutions to incorporeal objects are useful in a much wider variety of situations.
