If you lose a regular unit you need hammers to replace it, if you lose a summon you lose next to nothing. You can summon it again with full health on the next turn.
If you know what you are doing it's impossible to lose a stack of summoning conjurers vs the same numer of tier 3 units (unless they have blitz which is far away). The tier 3 units might have a higher strength but you have 3x their number in summons. Just use the summons from the first 2 turns to attack and the new ones to defend your conjurers. Even if no enemy unit dies from the attack they still can't kill a single conjurer on their turn. They will be damaged after fighting 2x their numbers in summons and on your next turn you can attack again (or they attack which leads to the same result). Eventually the tier 3 units will go down without ever fighting a conjurer. And for every tier 3 unit that gets killed you have one more summon per turn you can use for attacking instead of defending.
If they decide to hide in a city you just pillaging every tile in sight with no risk to your conjurers.
