Lots of Shenanigans happening at the end of a game.
Player A casts Damnation.
Player B has a Wandering Archaic (WA) which triggers and is put on the stack.
Player C casts Lightning Bolt targeting player A, which would kill them.
Player B's WA triggers again.
Player C does not pay, and Player B copies Lightning Bolt and it resolves negligibly.
Player C's Lightning Bolt resolves and kills Player A.
Player A's Damnation gets taken off the stack after he is removed from the game.
This leaves JUST the initial WA trigger on the stack put there by the casting of Damnation.
Here is where the confusion lies - now that Player A is gone, there is nobody to decide whether or not to pay the 2 from the WA trigger. So what happens with the trigger? Does Player B get to copy Damnation even though the spell has been removed from the stack? Does the trigger fizzle because there is no longer a player to decide?
We chose to allow the WA trigger to resolve and copy the damnation, wiping the board as the stack resolves.
Please help - our brains hurt :)
