How about this:
If an effect has a trigger, its source card must be in play for the effect to resolve.Exception: If a card has an effect that triggers when it is discarded (or in the case of a character, when he or she is discarded or killed), the effect still resolves, following the action procedure.Example 1: Cave Troll's Chain. If an exhausted Cave Troll bearing
Cave Troll's Chain takes its last wound during the archery phase, the Chain cannot be used to wound an archer companion because the Chain is discarded before its effect would resolve.
Example 2: Corsair Marauder. Same result as above. If the Marauder is killed before his effect resolves, the effect would not resolve.
There seems to be a contradiction in the 8/13/07 CRD between the "playing a card" and "void" entries. The "void" entry says a non-site card remains in the void until all of its effects have resolved, and then it's placed in play (or in the discard pile if it's an event). The "playing a card" entry says a non-event card is placed in play (step 3) before responses to the playing of the card happen (step 4). While the card is in the void, the entry also limits actions to examining the card, meeting requirements, and paying costs (steps 1, 2, and 3, respectively). Since the "playing a card" entry is more detailed that's what I went with.
However, if the Marauder is to work like Decipher intended, then an additional step can be created between steps 3 and 4:
3.1. If The Card has game text on it that triggers "When you play..." The Card, it happens now.Note that other responses or triggered actions that respond to the playing of The Card still happen in step 4.
Example 3: Shagrat, Captain of Cirith Ungol. Same result as above. If Shagrat is killed during a skirmish before strength has been totaled, his effect would not resolve.
