A player, 8 February 2012
Because of the order of effects on the card, can one use Temple of the Waystation's overlay and transfer effect to result in a game state where a non-henshin has two weapons because the target of the overlay was a kensai with a weapon? Or is the second weapon discarded?
Relevant text: Waystation of the Path Reaction: After another player's action targets your performing Henshin, target another of your Personalities: The Henshin is reborn. Transfer his attachments and tokens to the other Personality. The action's effects that would destroy your Henshin instead overlay him onto the Personality.
Kensai: May attach two Weapons. (Rulebook glossary)
The Game state: Personality A: Asako Yorisada with a Wyrmbone Katana. Personality B: Any Kensai with a 2nd Wyrmbone already attached.
If Yorisada is targeted with a kill action and I use the stronghold targeting the Kensai, the stronghold transfers the weapon. Then the stronghold overlays Yorisada over the kensai. As the personality now lacks the Kensai trait, but has two weapons, do both Wyrmbone Katanas remain in play?

Yes, if a card has the ability to have two weapons and then loses that ability due to another effect, he does not have to discard one of the already attached weapons.
