Lao Beifong, Overprotective

Creatures can't attack you or planeswalkers you control unless their controller pays {1} for each of those creatures.

When Lao Beifong, Overprotective enters the battlefield, you become the monarch.

"Of course it doesn't change the way I feel about you Toph. It's made me realize something...I've let you have far too much freedom. From now on you will be cared for and guarded 24 hours a day."
