Official Rulings for Leyline of Punishment
8/15/2010 : After all players have decided not to take any more mulligans, if the starting player has any Leylines in his or her hand, he or she may put any or all of them onto the battlefield. Then each other player in turn order may do the same.
8/15/2010 : Leylines that start the game on the battlefield aren't cast as spells. They can't be countered.
8/15/2010 : After each player has exercised his or her option to put Leylines onto the battlefield, the first turn of the game begins.
8/15/2010 : Spells and abilities that would normally cause a player to gain life still resolve, but the life-gain part simply has no effect.

8/15/2010 : If an effect says to set a player's life total to a certain number, and that number is higher than the player's current life total, that part of the effect won't do anything. (If the number is lower than the player's current life total, the effect will work as normal.)
8/15/2010 : Damage prevention shields don't have any effect. If a prevention effect has an additional effect, the additional effect will still work (if possible). Spells that create prevention effects can still be cast, and abilities that create prevention effects can still be activated.
8/15/2010 : Static abilities that prevent damage (including protection abilities) don't do so. If they have additional effects that don't depend on the amount of damage prevented, those additional effects will still work. Such effects are applied only once per source of damage.
8/15/2010 : Effects that replace or redirect damage without using the word "prevent" are not affected by Leyline of Punishment.
8/15/2010 : If a creature is dealt lethal damage, it can still regenerate. If it does, the damage marked on it will be removed from it.
