Card idea: Bilk Investor

Nice. Not too strong, but it could be very helpful, because you can use your +vote in more than one referendum in that given turn. I don't know if it is worth the addition to a deck. But I think it could be interesting. I'd give it a try.

Camarilla is already the best voting sect, an ally exclusive for them seems unnecesary, although I like the idea, I think it is too strong as it is not unique. It can stop a rush from a stealthless vamp or with unmasking even more. Noturn untaps you but gets burnt during untaps and it is a great ally, one that costs 1 blood disciplineless clanless, imagine a for/obf prince deck with cloak and veil. Better than having vote modifiers and rush defense at the same time. I would do a deck with 10 of them.

Hm, what about adding a "can't block vampires"-clause.

I think that being not unique is what´s challenging it not to be overpowered.
The way I see it, Mylan would be a similar ally. Comparing it, this one getting burnt when bleeding and being unable to block vamps could be a way to make it a good but not a tremendous card. Anyway, in a given situation this card could lead to a major vote control which ain´t that easy normally. I would do the card this way:
Name: Bilk Investor
Cardtype: Ally
Cost: 1 pool
Uniique Mortal with 1 life. 0 strength, 1 bleed.
Requires a Camarilla vampire.
During a referendum The Bilk Investor may tap to give 1 additional vote to a titled Camarilla vampire you control. Once each combat, he may dodge as a strike. Bilk Investor cannot block vampires.
I know it is a completely different card.
My two cents

remove "to a titled camarilla" and use: "to a camarilla vampire. A minion can only gain one vote from a bilk investor per turn".

add "The Bilk Investor may tap to give 1 additional vote to a titled Camarilla vampire you control during a referendum."
