Here's a discussion about the deck in another forum.
http://www.themanadrain.com/forums/viewtopic.php?t=21027There is also the aether vial based U/W/r fish deck that was on the board a while back.. if you search for it you should find it.
I think if you are limited by funds, then white fish has a slightly better chance than red fish do. The inclusion of meddling mage and Swords to plowshares make the deck a bit more resistant to ownage at the hands of oath. If you are having problems with workshop aggro I think white fish would have slightly better game against it but I haven't really done the testing.
