Two things are pivotal to the strategy. You must take the Church Leader High Saint Elienai and the Church organization advantage Divine Meditation. Besides Elienai you should take a full sweep of Inquisitor Warriors, you shouldn't need much healing if done right.Just having a character in Elienai's large control zone of 12 inches allows you to use Gnosis rolls after you've seen the result. This is a HUGE advantage because you don't waste the few Gnosis points you have but only spend them when you need them. In addition Elienai can deny an opponent's use of Gnosis so they don't get the extra die roll to achieve desired results. You can also as an alternative action grant every warrior in range of her an extra die for Dodges and Attacks. Potentially you can roll 3 dice with Gnosis. But it doesn't there, the organization advantage of Divine Meditation allows you to reroll once per turn. So if that attack is really pivotal... you can roll 6 dice. In Anima Tactics you're normally only rolling one die, so potentially getting 6 dice to roll and choosing the favored result is a MASSIVE advantage.
With those expert dodges you won't be healing your soldiers as often. Also, Elienai can use "Door to the Beyond" to bring them back to life at a sacrifice of some of her own. The disadvantage is that rolling too high can kill her. But with economical Gnosis use and the reroll ability you can make the odds against this pretty good. I always take the advantage card "Dragon Blood" which gives you a chance of bringing a character back to life. Again, rerolling increases your odds of not only being successful but having better success. So the odds of losing Elienai when she is at full health are quite low. Though using warriors like Nero or Xavier who can self-heal helps a bit to save the need to use Door to the Beyond.
Another trick I can use for health on one of my characters is the card Aberration power. Normally few people take this card because a bad roll on activation can have your character removed from the game! But with this Church force you're the master of rerolling, simply use Gnosis if you need it... and even a reroll if you're desperate. I'm still getting the timing of when its best to use the card, but my last game saw it used to great effect. In playing against Empire and Samael the thing to watch out for is your opponent's critical attacks and getting sniped. Do your best to control both and you should be able to win with this strategy!
