Valorne, Governor of Certa

Tax 3 (At the beginning of your upkeep, you may tap three other untapped creatures you control.)
Whenever Valorne's tax is paid, put an apprehend counter on target creature with power less than Valorne's power. That creature can't attack or block for as long as it has an apprehend counter on it.
"As long as I'm governor, my empire shall be the strongest on the plane."
