Robert Baratheon, Usurper

When Jared Carthalion, True Heir enters the battlefield, target opponent becomes the monarch.
You can't become the monarch this turn.

If damage would be dealt to Jared Carthalion while you're the monarch, prevent that damage and put that many +1/+1 counters on it.

"Robert was never the same after he put on that crown. Some men are like swords, made for fighting. Hang them up and they go to rust."
