A player, 4 March 2008
Lets assume I have no personalities in play, and 3 of my provinces are face down (for simplicity). The only province that is face up holds a Daigotsu Takayasu. My opponent is about to destroy one of my Provinces.
Can I use Takayasu's trait to give him the Shugenja trait, and target him with Imbue Chi's Reaction?
Daigotsu Takayasu Spider Clan • Shadowlands • Lose 2 Honor. Once per game, before Takayasu enters play: He goes through his Gempukku. Permanently give him Samurai, Shugenja, or Monk.
Imbue Chi Kiho Reaction: Before battle resolution destroys one of your provinces, if you control no Personalities, target a face-up Shugenja in any of your provinces: Turn all cards in your provinces face-up. Bring into play any number of face-up Personalities in your provinces waiving costs.

No.
You can't use a keyword not already there (Shugenja) to play a card (Imbue Chi) that's effects (bring Personalities into play) eventually trigger another effect (gempukku trait) that cause the keyword to appear.
