Trostani Discordant

That third ability is the wrinkle that earns this Trostani her surname. The anthem and the two lifelink Soldiers read as a clean go-wide payoff: a body that pumps the team and pays back a chunk of its own cost with the tokens it makes on arrival. The end-step clause is doing something stranger. At the beginning of your end step, every player regains control of all the creatures they own. The design logic is corrective, and it works across the whole board rather than defending any one color's tricks. Theft effects lean on the fact that control and ownership are separate things in the rules: Control Magic keeps a creature indefinitely, Act of Treason borrows one for a swing, and blink effects like Flickerwisp reset a stolen body under new control to make the theft stick. Trostani Discordant undoes that whole category of creature-stealing on a recurring clock. Any creature anyone stole reverts by your end step; any creature forced onto an opponent comes home. The trigger is symmetrical and mandatory, so it snaps your own borrowed threats back to their owners exactly as reliably as it rescues your creatures from someone else, and any temporary-control effect hoping to stretch a stolen creature past a turn dies on her watch. Four toughness ducks a lot of damage-based removal, and the immediate token swing means she replaces herself even in a bad trade. What makes her more than a green-white lord is that she taxes an entire category of creature-theft just by standing on the battlefield.
