Yes, I'm saying no to the most basic anti-mage spell, because the ability to absolutely stop a mage from using magic is extremely powerful. I'm alright with Anderiel's AOE magic nullification, because you can at least move out of it, but something that prevents another from using magic absolutely is sorta stronk. Because mages without magic are only human, and that means that all the top-tier mages become meat-shield fodder after they're silenced. Especially against Thao kiddies, who can burst them down in physical speed and strength.

Perhaps she has a spell that allows her to counter a single other spell instead? Something like a spell shield.

I just feel that Pool of Dread is iffy because it sucks up LIFE. I'd be fine if it sucked up mana or something, but eating up life force just sounds really powerful, especially if it's an AOE.

EDIT: Now that I think about it, has there ever been a Silence in animu magic combat? No, right?
