Juat off the top of my head, but would a B/G version running Skullclamps and Cabal Therapy in combination with stuff like Xantids, ESG and some other utility or acceleration creatures be an idea? (You could even pop in Eternal Witness)
The problem with that is the lack of Control elements to protect your combo, i.e. they aren't as resilent to counter-disruption. Another problem along the same lines is that since it would have a draw-mechanic based on Skullclamp it would just roll over and die to a Null Rod, hell you may as well scoop if you're playing against Fish.
Not that it's entirely a bad idea, but the strength of the design is drawn heavily from Hulk builds, obviously, and is applied here because of the easier shift in deck design based on card availability. Fish is seen a lot not just because of how good it is, but also on how easy it is to build for the majority of the Vintage community; and so the same applies to this to an extent.
Also...
You might notice I have Tel-Jilad Justice instead of Oxidize. This is because I think it's just plain better, but aside from that I've seen some people trying Oxidize to dodge Chalice. Well, that's a nice game-plan and all, but honestly it doesn't work because Duress is your own enemy here. If an opponent is on the play, even if they can cast a Chalice for 2, the smartest thing they will want is a Chalice for 1 out quick. This will stop Duress, Brainstorm, Ancestral, and Mystical, giving them a lot more freedom, and so Oxidize doesn't help at all. On the draw they'll drop a Chalice for 2 as soon as possible, then go for a Chalice for 1 above all else. The end results is that means the smartest Sideboard option would be Deeds over Justices; however this could put a strain on the 3 Bayou mana base for Black support. So in the end, that particular aspect is up to personal taste, because it won't matter that much.
