Fish is basically a deck that is based on cheap disruption in order to slow the opponent down an beat him with few tool-creatures like meddling mage etc. The problem is that this will cause a lack of speed that hurts against almost any aggro deck. To add green makes it more aggro like Legacys Threshold. So a few of my mates who have no access to power do so and created various 3c and 4c builds.
Simply they grab a Legacy Theshold an realize what to beat in Vintage ... Tyrant Oath, Flash, Staxx, GaT, maybe various Storm-combo ... so the deck changes a bit due to the metagame. Few of them I want to show here.
Take a look on the colors. Most of my comunity decide to run 4c that often results in a very ... lets say ... interesting mana base, that do the job. But not well. I think that 3 colors is pretty good. The descision is that color to drop. Loosing StoP and Meddling Mage hurts but green gives you access to Goyf and LftL. Goyf gives you aggro and Life from the Loam a softlock via Wasteland. Some things I really can't understand is for example why you want to run Gush without fastbond. Moreover you run black but dismiss Vamp. and Dem. Tutor to grab your essential spells like Ancestral or echoing truth. ET is useless if you have to topdeck it, facing a mob of EtW-Tokens. I also miss Stifle, a control-element due to the mass of Fetchlands, EE, Strom-spells etc. At last you reduce your Duress-effects to add vial. You are not that aggro that you have the quantity or quality of beaters to simply overrun any opponent ... you always write that you want to get rid of creatures/threads of your opponent. Duress/Thoughtseize do this pretty cheap/fast (won't miss it if you face Flash). Rootmaze is nice because is slows the opponent down, but you have to ask yourself if Nullrod isn't simply the best. Finally a word to EE. You will not clear your own field if you play it right. Clear the field and then go for gold with your creatures ... please not the other way round

It will help you also with the named EtW, Goyfs, Dryads even Oath of druids.
Sorry if this post seems a bit harsh but I think you should basically decide if you want to play fish Or playing GaT with Bob (which is simply stupid because of all the expensive spells a la FoW, Misd. or Gush). With your access to power I would prefer playing GaT anyway.
