Charity

Identify the player with the lowest life total, whenever you would gain life, that player gains that much life instead.

If the player with the lowest life total deals damage to you
or your permanents, targets you or a permanent you control with a spell or ability, or causes you to sacrifice a permanent, sacrifice Charity.

If you have the lowest life total, whenever you would gain life, gain twice that much life instead.
