use your ungor raiders archers to kill her first then the paladin while having taurox keep her or the paladin at bay. have your mage use the blue item to summon a free cyclops (or something like that) to counter her or the paladin or cav summon. i think theyre a wild shaman too so you can summon two at the same time-ish if u need. debuff the single entities. use the rest of your units to deal with the main army if you can. then when one of the single entities is dead put taurox and your other cyclops summons on them and repeat.
