Creatures you control have fear. (They can't be blocked except by artifact creatures and/or black creatures.)

When Intimidation Campaign enters the battlefield, each opponent loses 1 life, you gain 1 life, and you draw a card.

Whenever you commit a crime, you may return Intimidation Campaign to its owner's hand. (It returns only from the battlefield. Targeting opponents, anything they control, and/or cards in their graveyards is a crime.)
