A player, 26 January 2014
First off, Koan's Robes states that it negates the first destruction of cards in the unit from another player's card.
If I use Unsettling Gathering to steal my opponent's:
1. Fueling the Flame, can I use the second ability "Fire Battle: Bow this Shugenja to make a Ranged 6 Attack. Destroy this Shugenja." and have Koan's Robes negate my shugenja's destruction?
2. Blood of the Preserver, can I use it's ability "Maho Battle/Open, *: Target your dead Personality. Bring him into play if his Gold Cost is equal to or less than the amount paid. Lose 2 Honor. Destroy this Item." to bring back my dead Personality and have Koan's Robes negate the Item's destruction?
Conversely, what if I steal my opponent's Koan's Robes? Does the trait trigger from my own cards?
