Are there rules anywhere clarifying which player's Discard Pile cards go into? eg.
(i) If I attach a card to an opponent's character and that charcetr is destroyed, into whose discard pile does the attcahed card go?
(ii) If I take control of an opponent's charcater "until the end of the phase" and that character is destroyed during the Phase, does it enter my or the opponent's Discard Pile? If mine, does it then move to Opponent's Discard Pile at the end of the Phase?
