The idea in general is to use Light attacks to inflict Daze / Stun conditions while inflicting damage. To this end, Malakai's Bassilica usually comes out early, and Hawkeye usually is one of the first Enchantments cast on the Priestess. My first pieces of equipment are nearly always the Ring and the Robes. When I go on the offensive, I like to have Bear Strength and the Staff out, and when I want to play a ranged game I use the bow. Having the weapon attacks saves mana.
The specific Creatures to be brought out generally depends on the opposing Mage; they each have abilities that complement specific strategies. Three of them have Light attacks, Brogan cuts through armor, etc. In particular, I like to have Dorseus out with the Asryan Robes equipped since that nearly forces someone to play a Deathlock or Poisoned Blood fairly early. Joseph Trublood is generally good in support of nearly any creature combination.
In addition to the Light attack spells, the Force Hammer is primarily in the book to deal with a Deathlock, Swells are for Battle Forges, and Tsunami (along with the Pillar of Righteous Flame) is general swarm defense.
The book can play Temple-heavy (if I let the enemy come to me), or just to have one or two out and go on the offensive. I like the option to deploy the Messenger from the Temple of Asyra to get passive healing during Deployment. On only having six creatures and a Temple of Asyra... I tried to play without the ToA, but having it just helped in so many cases, some action advantage, the ability to cast some of the full-action cost spells and the ability to use my actions to attack.
Did I miss anything that you are curious about?
