Wikr, Sower of Nightmares

Wither
At the beginning of each player's upkeep, that
player may put a -1/-1 counter onto a target
creature besides Wikr, Sower of Nightmares.
Whenever a creature dies, the last player to put
a -1/-1 counter on it draws a card and creates a
2/1 scarecrow artifact creature token with Fear.
