Player A has a face down Ceasefire and a facedown Sangan. Player B has a face down Ceasefire and a facedown Spirit Reaper. Both players have 500 LP. Player A activates Ceasefire and Player B chains his Ceasefire. Now, for the question. In this scenrio, would Player A lose as Player B's Ceasefire activates first, or would the chain have to resolve fully first which would result in a tie?
