After the initial two rounds of summon and control, is fighting with(not against) an elemental like:
Sorcery: command this round, a thick darkness attacks at the end of the next one. Now that everyone is dead, repeat next 2 rounds for new targets.
Like Bending(avatar): hit someone with your sword, and a whirlwind will knock them out (fix command, attack whoever I strike)
Like having a dog: point at the troll, whistle and the fire dog jumps on her while I do my stuff.
I would love to know how you handle it, cheers!
