A player, 21 October 2009
Togashi's Guidance: Reaction: After an action ends during which any Rings entered the discard pile from your hand or from your focused cards, if you are a Dragon Clan player, discard this card: Put one of those Rings into play or into your hand.
Imperial Artificer: Bow this card: Produce 2 Gold. If this pays for a Follower or Item attaching to a Samurai, you may draw a card, then discard a card.
I announce that I intend to attach a 2 gold cost weapon, normally in as a limited action. As a cost of that action, I bow artificer to pay the cost. This is paying for a weapon, so I draw a card and then discard. The discarded card is a ring. I continue through with the action and attach the weapon. After the action resolves, can I play the ring I discarded from artificer? An *action* does not discard a card, but rather the trait of artificer. The trait was triggered during the action.

Togashi's Guidance does not require that the cards enter the discard pile because of the action, only during it. You may play the Ring after discarding it due to Imperial Artificer's trait.
