Z Winterowskich FaQ:
DOCTOR DIANA (INQ)
If DOCTOR DIANA is given a TAINTED, could she then also heal Dark Legion warriors?
Absolutely! And if she becomes a full-blown Dark Legion warrior with no more corporate affiliation (like through a DARK VISITATION) then she may ONLY heal the Dark Legion.
ART OF SUMMONING
If I use an APOSTATE, or other Brotherhood warrior completely turned to the Dark side, to cast a SUMMON TROOPER, he may only pull out a Dark Legion warrior?
Yes.
What happens if the Brotherhood warrior is only "tainted" (and is therefore a Dark Legion warrior but still has his Doomtrooper status - like with a TAINTED card). May the Brotherhood warrior Summon either Doomtroopers or Dark Legion warriors?
Yes. In this case, the Brotherhood warrior is a Dark Legion spy, and may cast spells for either group. Just make sure the Inquisitors don't find out about it...
What if I use VALPURGIUS to cast this, since he can cast any spell on any warrior, does that mean he may bring either a Doomtrooper or a Dark Legion warrior out?
Yes. Who knows what his schemes are, but if he wants to put CARDINAL DOMINIC in play, he can do it with a SUMMON HERO!
