It is in fact a new fish deck. Interesting cards, but I don't find strong synergies from a first sight:
3 GSZ, but only 7+3 green creatures, 5 of them 3CC. GSZ fetching an arbor is countered by misstep, looking for a trygon is hard to cast under spheres, and in general is countered with flusterstorm, while hardcasting creatures it's not. It seems that often you would prefer a creature in hand than GSZ.
Snapcaster (isn't it Tiago instead Taigo?) it's being massive, and I like the suite of sorceries and instants available. But I'd prefer to make this deck more oriented to flash, with Vendillions and so. Being this a fish deck with null rods, stifle could be a nice add-in in order to cut fetchlands
Edric is a great creature, but this deck has only 10 creatures, and any has flying or another kind of evasion. While Edric makes them a must block, Edric alone it's a bit slow. I'd like him with delvers or sages of epityr, in a tempo style.
Is Dryad Arbor better than Noble Hierarch in this deck? With GSZ it gets better, but against fish and mud you usually would prefer noble. Arbor isn't counterable, but GSZ -> Arbor it is.
Nevertheless, I find interesting the deck and I would look for match-up explanations
