Text (SM): If you would gain life, you gain twice that much life instead.
The effects are cumulative. If you have two in play you gain 4 time as much life, and if you have three you gain 8 times as much. [Shadowmoor FAQ 2008/04/21]
If an effect sets your life total to a certain number, and that number is higher than your current life total, that effect will cause you to gain life equal to the difference. This card will double that gain. For example, if you have 13 life and Blessed Wind causes your life total to become 20, your life total will actually become 27. [Shadowmoor FAQ 2008/04/21]
This card does not cause you to gain life. It causes other life-gaining effects to give you more life than they would have. [Shadowmoor FAQ 2008/04/21]
