You need three cards for this to work:

 

Transcendence - Enchantment from Torment

3WWW - You don't lose the game for having 0 or less life.
When you have 20 or more life, you lose the game.
Whenever you lose life, you gain 2 life for each 1 life you lost.

 

Donate - Sorcery from Urza's Destiny

2U - Target player gains control of target permanent you control.

 

Blessed Wind - Sorcery from Prophecy

7WW - Target player's life total becomes 20.

 

Basically what you do is play Transcendence, and Donate it to another player, then (if they don't already have 20 or more life) cast Blessed Wind on them, so they have 20 life, and thus they lose the game thanks to Transcendence.
