Defender of Royal Protocol

When Defender of Royal Protocol enters the battlefield, you become the monarch.
Pact — Whenever a creature an opponent
controls would deal damage to you, you may gain
a debt counter, then pay {1} for each debt counter
you have. If you do, prevent that damage.
That's a standard fee in this line of work your
majesty. You never really liked the snot-nosed brat
anyway, right?
