Reading the Forums, I've ascertained that "Controller" on charm means your mage. This means that the creature can still attack your creatures and vice versa without breaking the Charm. However, would having your mage Push the creature through a Wall with a Passage Attack break the Charm? The Push isn't actually an attack and isn't what does the damage, the Wall is what attacks and damages the creature....So I'm assuming its safe to do this without breaking your charm, but I'd like to be sure.
