Near the end of the battle, I like to 'corner' one depleted enemy RANGED unit with two of my strongest (most hitpoints per creature) stacks. If there is at least ONE hex between the enemy ranged stack and one of my own stacks, the enemy stack will never close in and attack in melee, no matter how weak/strong my unit is. So, if I cast the poison cloud on the enemy, almost always one of my stacks will be under the cloud, taking damage and returning mana (with mana spring). Then it is enough to cast one life totem near the unit under the cloud, and another one in the middle of the other 3 stacks on the other end of the battlefield, healing the odd damage provoked by the depleted enemy stack. And, if the enemy ranger is capable of fire/poison attack, so much the better: two Mana Springs are better than one

Last night I was lucky attacking a castle (I think the one with that Earl in the Mines). At the end, I had one enemy goblin catapult stack with only one goblin in it. Obviously, poison cloud was out of the question, so I cornered the goblin, positioned the Life Totems as described, and all I had to do was to wait for the Goblin Catapulter to cast his extra ability, the fire ranged attack. That fire provokes burning for 3 turns, so I invest 5 points in Mana Spring on the afflicted stack, and get in return 15 mana from the spring. The totem heals the tiny damage (so no need to resurrect anyone) and Lina's Chargers are retrurning more mana. I know this tactic is known, but it was fun to experiment it by myself

Zero losses! (no sh*t, Sherlock?
