I've only recently started playing the game, and am only just learning some of the intricacies of the game - I hope my first questions aren't something obvious I've missed!
1. Do characters who change control retain all power/gold on them?
I've seen no ruling that implies otherwise (only stating the loss of attachments), but as stealing a Berric Dondarrion or stacked Maester with Reek seems like a big game-changer, I wanted to double-check this.
2. How does the following scenario resolve;
First & Active player declares a challenge with a deadly character
Defender is at 14 power, and blocks with a renown character of higher strength
As I understand it, first the winner is determined (defender), second the claim is satisfied (none, it's a successful defence), third power is not awarded for unopposed, and fourth, passives trigger. Since deadly and renown trigger at the same time, the first player chooses deadly to resolve first, killing the defender's renown character.
What I'm not sure of here is if the defender claims power for renown, or if the entire moribund state will have resolved before he has the opportunity to trigger his passive. Or, in more general terms, if effects which resolve simultaneously (an order of which is determined by the first player) can cause the first event to prevent the second from happening. Secondly, I'm not sure if power on moribund characters counts towards victory totals (I assume it does, as once again there's no explicit statement otherwise).
