Forum:Reaching 0 life in the middle of a chain

the question i have is this. if im dueling someone and we both have 500 lifepoints left. i use poison of the old man and choose to deal 800 points of damage to my opponents life points. they than chain with their own poison of the old man and do the same to my life points. nothing else is added to the chain. his eff resolves and brings my lp down to 0. the question is will i lose right than or will the chain have to finish resolving first to determine whos won. or in this case a draw--68.10.77.174 (talk) 17:34, March 18, 2013 (UTC)
