Leyline of Punishment

Aug 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.

Aug 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.)

Aug 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.

Aug 15, 2010 · Effects that would replace gaining life with some other effect won't be able to do anything because it's impossible for players to gain life.

Aug 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.

Aug 15, 2010 · Effects that replace an event with gaining life (like Words of Worship's effect does) will end up replacing the event with nothing.

Aug 15, 2010 · Effects that replace or redirect damage without using the word "prevent" are not affected by Leyline of Punishment.

Aug 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.

If a cost includes life gain (like Invigorate's alternative cost does), that cost can't be paid.
