Sadako Yamamura

When Sadako Yamamura enters the battlefield,
each opponent creates a colorless 0/1 TV
creature token with defender and "At the
beginning of your upkeep, put a curse counter on another target nonland permanent you control
without a curse counter on it."
Whenever Sadako Yamamura dies or is
exiled, exile all creatures with curse counters on
them. Each opponent discards a card for each
nonland permanent exiled this way.
