Natasha Romanoff

Deathtouch, haste
When Natasha Romanoff enters the battlefield,
you become the monarch.
At the beginning of your upkeep, if an opponent
is the monarch, create a 1/1 black Assassin
creature token with deathtouch and haste.
"I'm my own woman, first, last, and always!"
-Natalia Romanova (Earth-616)
