Killmonger, The Conqueror

First Strike, Menace

Conqueror’s Ambition — Whenever a creature you control deals combat damage to a player, that player sacrifices a creature or discards a card.
Scorched Earth — Whenever a creature an opponent controls dies, you may pay {2}. If you do, create a 1/1 black Warrior creature token with haste.

"A king sits idle, but a conqueror reshapes
the world."
