NEW CARDS. From the Primogen of the Baali!

Synner-G:
Consider with a single (zero cost) card, he can bleed for 2 at 1 stealth. Or with a laptop he can do that without ever playing any other cards. On a 3 cap. That's easily worth a single discipline point.
The fact that the one point he does have is just makes it even better.
His untap special is probably worth about a half point.

El Diablo Verde:
A suitable drawback might be one of the below;
El Diablo Verde cannot have or use equipment.
El Diablo Verde cannot use ranged strikes.
-1 stealth.
I can think of others, but I think these best fit the idea of a pro-wrestler vampire, and still leave him very usable.

Naomi McKellar:
Depending on the type of spy she was, presence might be more appropriate. As a card I think obfuscate works better.

Falstaff:
Even with your Art of War card, I still think he's underpowered. At a simple numbers game you're pricing his research area special at about 1.5 - 2 points. Additionally, his disciplines don't work well with either of his specials. Superior would fix that, or basic of an additional combat discipline and your Art of War card.

El Diablo.
Yeah -1 stealth would be good. "You can see him coming a mile away!"

Synner-G
Remember that Laptop cost 1 pool. But then again, it always does. Maybe wording like this: "Sabbat: Synner-G untaps if he successfully equips with a Laptop Computer. Laptop Computer gives him +1 stealth when bleeding with Computer Hacking.
Slightly reworded, and special made a little weaker.

Falstaff
How about discipline spread:

Now he is nicely pared with Toy. Maybe Toy now may be useful.

Thanks for your views. Much obliged!

********Here is another vampire from the Montreal book**********

Whale


Cap 3
Potence reaction cards cost Whale 1 less blood to play. In combat Whale may not maneuver. Actions other than actions to enter combat, hunt or to inflict damage cost Whale an additional blood to play.

Now El Diablo and Whale should be quite different groups. 5 & 7 maybe.
