Walhart, Conqueror of Valm

Haste, indestructible, vigilance, trample,
first strike, menace
When Walhart deals combat damage to an
opponent, you become the monarch.
At the beginning of your end step, if you are not
the monarch, sacrifice Walhart.
"Behold: I am Walhart the Conqueror! And you are
but a pebble upon my path to immortality."
