Who Stole Donut's Diary

When Who Stole Donut's Diary enters the
battlefield, secretly choose an opponent.
At the beginning of your upkeep, each opponent
tries to guess which opponent you chose. Then
reveal the player's name. If a plurality of
opponents chose the correct player, that
opponent exiles a creature they control, and you
and the other opponents draw a card. Otherwise,
you and the chosen player draw three cards, and
the other opponents exile a creature they control.
Exile Who Stole Donut's Diary.
