I'm having problems understanding Eye for An Eye. Suppose I am Targeted by a lightning bolt, which would kill me. In response, I play Eye for an Eye: How does Eye for an Eye resolve? Since Eye for An Eye needs to check if I'm damaged to resolved, and if, once we check the damage, I'm dead, does Eye for an Eye get stuck on the stack, never resolving? Does this situation change in multiplayer? Thanks!
Eye for an Eye is one of the older cards that you need to pretty much completely ignore the printed worded for. Be sure you look up the current oracle text for older cards like this one. Here’s the current oracle text for Eye for an Eye: “The next time a source of your choice would deal damage to you this turn, instead that source deals that much damage to you and Eye for an Eye deals that much damage to that source's controller.”
Eye for an Eye has a replacement effect, so when Lightning Bolt deals its damage to you, Eye for an Eye also deals 3 damage to Lightning Bolt’s controller. Then you lose and leave the game once state based actions are checked.
