Chuashek came to me with almost full mana (60+, I think). His army wasn't exactly weak either (about 20 rogues, 6 cyclops, 60 orcs, and a hundred dogs). The most I could get out of the battle against him was losing 80 gnolls. Tsipesk slightly drained his mana at the citadel, but also not significantly (it was somewhere around 40+). So, I decided not to attack them right away. There wasn’t enough money for archers because of the late capital (215).
It is possible that these problems with green and brown are just my luck. To roughly understand what happens each time, you can download the save from here.

By the way, Chuashek and Tsipesk, after learning additional magic from our castles, start casting haste and slow (considering our resistance, Tsipesk tried to cast slow three times in a row), and not only use offensive spells, so attacking them later might not be the worst option.
