@N_B and the Vladek Visage Conundrum!
I now entirely agree with your take on Vladek's Family Relations. The keyword being Legacy really clicks.
Still on the fence about giving Vladek powers, but if he did, It would be entirely from artifacts, or other outside sources and nothing from his own self... correct??? That's what I get from the limited LEGO Co. Storyline I've read...
Concerning the Mirror-Halls duel, I believe simply that the more extesive usage of the Presice and Manipulative Vladek makes him the one we will use.  The one shown in the Mirror Halls was when folks were still fiddliing with stuff. (Like how Matthias would just suddenly go ranting, lose his temper, or would otherwise be written unlike the Matthias we now know... :P Ah. Good times.) This reminds me, I GOTTA POST MORE P.D.!!!! :O
