A player, 23 May 2011
My opponent is bringing a Shadowlands holding (let's say the Dark Oracle of Water) into play by using the Shadowlands Horde stronghold's (or the Festering Pit of Fu Leng's) ability to reduce a Shadowlands card's cost by four (or five respectively), making it 0. Later, I flip Plague of Locusts. Is the Oracle destroyed? I believe so, but I want to make it sure.
Relevant text
The Shadowlands Horde (stronghold): Reaction: Bow when bringing a Shadowlands card into play to reduce the gold cost of the card by four.
Festering Pit of Fu Leng (holding) Reaction: Bow at any time to reduce the gold cost of any Shadowlands card by five until the end of the turn. Lose 2 Honor.
Plague of Locusts (event): Destroy all Holdings in play that entered play for 0 Gold.

http://rules.l5r.com/Older_Card_Rulings ... of_Locusts: "Destroys all Holdings that entered play with a Gold Cost of 0, regardless of their current cost or whether Gold was paid anyway; does not destroy Holdings whose costs were ignored." Emphasis added. If it came in for 0G, it's locust munchies.
