A question about new Rhaegal from Music of Dragons:
Reaction: After an opponent's character is killed by a card effect, stand Rhaegal.
At first glance it's all clear: characters can be killed either by framework effects (military claim), or by card effects (those that say "kill a character"). However, it gets blurry if we look at claim replacement effects and certain other cards:
1) Some cards instruct a player to apply / satisfy military claim (Vengeance for Elia, Trial by Combat, Now It Comes To War, Maester Aemon (WotW), The Free Folk). Do these kills trigger Rhaegal?
2) Some cards replace normal claim with a kill effect (Mirri Maz Duur, The Seastone Chair). Do these kills trigger Rhaegal?
Note that we're currently operating under the premise that Rakharo triggers off characters killed by Mirri and Seastone Chair, because modified claim is still claim. Can a kill be caused by both claim and card effect? Or is it one or the other?
