You must assign at least 1 damage to each target.
You can’t choose zero targets. You must choose at least one target.
The opponent targeted for the life gain effect may also have been targeted by the damage effect. If this happens and the damage effect drops that player’s life total to 0 or less, the life gain effect will raise his or her life total above 0 again before the player would lose the game.
