Can you clarify the timing / actions of replacement effects
e.g.
Darkstar - If Darkstar would be discarded
Aeron Damphair - If AD would be killed
I'm under the impression that such effects means the card go to moribund and then get redirected instead of moving to its final destination
If someone plays Valaar and AD is "killed", what happens? when does the effect occur (in this instance I would put another cup character in play when the replacement effect kicks in
I'm also thinking of what happens when you discard Darkstar from your hand to save a character from being killed (via Maester of the Sun) ... Darkstar enters play and gets killed in the next step
Why does this happen ... the replacement effect that puts Darkstar into play ...before characters are killed
Finally ... if you discard a card from your hand does it go into moribund or straight into the discard pile
thanks
