Can you trigger Warm Welcome, choosing a card you cannot play, just to put that card on the bottom of your conflict deck?
(Similarly, trigger Kyuden Isawa to remove a spell event from the game).
- Duty, as an example, appears to be a valid card for targetting (it's a card in your discard pile).
- Based on KI ruling, Duty cannot be played. (assumption is that any Reaction/Interrupt cannot be played by WW or KI).
- The last line of Warm Welcome (If it is an event, put it on the bottom of your conflict deck) is not dependent on the card being played.
