Saw a deck that played Survival of the Fittest as well but ran 4 SSG's and 2 ESG's instead of Moxen, it did ran the Black Lotus but that should be cuttable for your deck. This allowed for 4 Chalice of the Void and 4 Null Rod. Furthermore it ran Welder + some giant robots such as Triskelion, Inkwell Levithian and Platinum Angel. Also some Gorilla Shamans and a bit of a toolbox with 2 Goyfs and some artifact/enchantment kill. The designer opted against Anger as he found it win more which agreed on. He ran one copy of Squee.
Now that deck totally rocked I wish I had a list but this is as accurate as I can describe it. It may not be Zoo but it was probably the strongest unpowered deck I have seen, at least for a powered metagame. I'm not so sure how it would be in a non proxy enviroment where people will run tons of creature hate..
Here is the deck you are talking about. At least the last version
// Red Green Control
// Lands
4 Wooded Foothills
2 Bloodstained Mire
4 Taiga
1 Mountain
1 Forest
3 Wasteland
1 Strip Mine
2 Bazaar of Baghdad
// Creatures
4 Simian Spirit Guide
3 Elvish Spirit Guide
4 Goblin Welder
3 Gorilla Shaman
1 Tarmogoyf
1 Ingot Chewer
1 Squee, Goblin Nabob
1 Stingscourger
1 Platinum Angel
1 Sundering Titan
1 Inkwell Leviathan
// Spells
1 Black Lotus
4 Null Rod
4 Chalice of the Void
4 Pithing Needle
4 Survival of the Fittest
4 Pyroblast
////////////////////////////////////////////////////////////////////
The deck is designed to be a "pain in the ass" for Control, combo and/or combo/control decks and it does the job pretty well.
The stacks matchup is pretty good : many permanents, welder+shaman and rod+strip.
The oath matchup is a very poor one (the side has to adress this pb).
The dredge matchup is not so bad even g1 (4 needle and 4 strip effects in main + platinium). Of course, some cards have to be added in side in order to deal with it.
The aggro matchup is not good (whether it is fish or shop/aggro) : only 1 tarmo is really not sufficent when you don't succeed in activating a welder. This has to be adressed with side.
In the end, this is a funny deck to play, that is pretty efficent at doing what it has been designed for.
Some cards to think about :
- root maze
- more tarmo
Some card i am not sure about :
- 1 tarmo
- pyroblast
- the 3rd elvish
- stingscourder and ingot chewer in main
