To quote Mark Rosewater from WotC R&D on the issue:

"Now many players then chime in that they are willing to watch their cards devalue if it allows others easier access to Type I. Unfortunately, this is not how all the players feel (and I’m betting there’s much more in the opposite camp). The day Wizards reprints Black Lotus we are taking thousands of dollars away from the player base. We are teaching them not to trust us as we will have broken a very serious promise. And most importantly, we are training them not to invest in cards in the future.

In short, it’s just bad business. What we gain would not make up for all we would lose. So, we’re not going to. R&D is becoming more and more receptive to the Type I community, but this is one issue where we are simply not going to budge."

So just give it a rest, it will not happen.

Personally I dont think that vial-fish can afford to squeeze in any spot removal that doesn't come with a body attached,
incatian javelineers may be a good creature to include together with a few bouncers if you are having trouble with welders.

It all comes down to what kind of meta you are facing, the rootwater thieves are good against medium-speed combo such as TPS and gifts but blow against shops and control with more than 2 winconditions. The bouncers are good against everything that runs tinker/DSC and javelineers are good vs welders.

I would try these creaturebases:

in a combo/combo-control-heavy environment:
4 factory
4 meddling mage
3 waterfront bouncer
4 rootwater thief
3 voidmage prodigy

in a welder-heavy environment:
4 factory
4 meddling mage
4 waterfront bouncer
4 incatian javelineers
2 kataki

And always run 4 chalice, 4 vial and 3 jitte (and maybe the 4th one in sb). Jitte allows every creature on the board to pose a serious threat, you really only need 1-2 creatures out to win with jitte.

 

Try switching the plows for waterfront bouncers and then remove some other creature like the kamis and kataki to add in 4 chalices main. Waterfront bouncers are mad against oath and dragon plus all the decks that like to play "find the tinker" against fish and also against random-zoo.dec.

First post btw.
