The Straw Man

Announce - Until your next turn, each creature
your opponents control must attack you if able.
At the beginning of your next upkeep, you gain
an alternate victory condition. You may activate
this ability only on your turn.
Victory - You win if you are announced, if you are
the first player to leave the game, and a source an opponent controls causes you to leave the game.
Alternate Victory - A source you control causes
you to leave the game.
