Tea Queen Natchesa

Deathtouch, haste
When Queen Natchesa enters the battlefield, you become the monarch. When this card is in play, the monarch may assign up to two sips of tea per turn to any target.
At the beginning of your upkeep, if an opponent is the monarch, put a 1/1 black Assassin creature token with deathtouch and haste onto the battlefield.

"The secret is: it's always tea time."
