Shrine to the Nightmother

When Shrine to the Nightmother enters the battlefield, create a 1/1 black Assassin creature
token with shadow and deathtouch.
At the beginning of each opponent's upkeep, if
they haven't named a creature that player may tap an untapped creature they control and name a
creature.
If a source you control destroys a creature named
by an opponent, draw a card and create a Gold
token.
