Standard green stompy deck, but with Battlefield Thaumaturge + either Polymorphous Rush or Icy Blast as a late game win con.
Not to much to explain here, so I will go over the mana base, and the combo.
First off, you may ask: you only have 7 sources of blue mana in the deck? Whats up with that? Well, the 2 Ilysian Caryatids produce 2 blue mana, so even just those will be enough to pull of a win.
Now to explain the combo: Play the Thaumaturge, this will make the Icy Blast only cost 1 blue, so this can be pulled off as early as turn 3 (not that you'd want to), but this will tap down your opponents whole board for two turns, allowing you to get through with your creatures more easily. But the main combo that I made the deck for was Polymorphous Rush. With the Thaumaturge on the field, the rush only costs 2 up front, and 1 blue every consecutive target. I know, that is still a lot of mana, but I really only need to copy say a Lovestruck Beast twice to finisht he opponent off.
Also note: With Shifting Ceratops, while you may think that since it has prot U, it is anti synergy with Polymorphous Rush. Well your mostly wrong. I have googled some rules stuff and have come to a relatively good synergy between the two cards.
Protection allows protection from being: Damaged, Equiped/Enchanted, Blocked or Targeted by the named card type; in this case blue (Think of the acronym DEBT). Now you may think, rush targets stuff! it does, but not the card your copying. So if you have a bunch of mana dorks, and you want to turn them into ceratops', Polymorphous Rush doesn't target the ceratops, so you can duplicate it that way.
Another interesting synergy is if you activate Shifting Ceratops's ability, and then copy it, I am 99% sure the copies retain the keywords, a pretty niche synergy, but even then not that game breaking, having like 3 5/4 tramplers.
Upgrades to this deck are simple. If you have the money, change the Colossal Dreadmaws with Elder Gargaroths, and the Paradise Druids with Sylvan Caryatids, and maybe make the deck mono green/gruul, cause this is a stupid idea
