I play in the same gaming club as wildrage and we answered the first 2 questions.
because of the wording of the blast you would nominate all models under the template as you put it so the new seishin wouldn't be affected.
But for the third question we are really annoyed by the fact that the effect is on the seishin and that at the time the effect is ``tranfered`` the seishin isn't in play anymore so would a rule marshal please help us with that?
