Zoo in pauper takes a hit because it lacks a number of vital cards (everything from loam lion to jungle shrine to woolly thoctar.)

However one of the most efficient 1 mana greens of all time is still there, Wild Nacatl, and its counterpart Kird Ape. After much experimenting this is my attempt to make a deck that plays a little like a modern/casual zoo deck in pauper. Running the hands out it has a pretty good chance of getting a 3/3 on turn one by using a forest and lush growth on turn 1 and then dropping a lotus petal for Wild Nacatl. Lush Growth, our petals and Nylea's Presence allows us to use some really good spot removal out other colors as well as getting our Kird Ape onto the field.

I added Khalni Garden as an easy way to block an attack turn 1 against some of the rush decks (stompy and infect for instance.)

To be honest it's not worth it. For starters, you have about a 45% chance of getting Wild Nacatl in your opening hand, that's less than half of the games you will play. The odds of you having a Wild Nacatl and a Lush Growth in your opening hand significantly less. You could play mono white Metalcraft/Affinity, and the deck would be more aggressive, and you'd have a greater chance of swing for 3 (or even more) on turn 2 with Ardent Recruit because you can play artifact lands like Ancient Den and CMC 0 artifacts like Bone Saw and Welding Jar.

I haven't played solitaire with your deck, but it's not going to be fast enough unless you have Lotus Petal in your opening hand, which won't happen most games. Even in the cases that you do have Lotus Petal in your opening hand, Artifacts and Burn are going to be faster than you. Generally speaking, multicolored decks (especially 3 colored decks) aren't good in pauper unless they are control decks (Tron, Mystical Teachings, etc. The reason Wild Nacatl is one of the most efficient one drop creatures of all time is because of powerful fetch lands that allow Wild Nacatl to consistently swing for 3 on turn 2 which is not possible in pauper.

Greetings from the competitive Pauper subforum! Card legalities aside, I just wanted to point out that there IS a tier 3 Zoo deck, but it looks a bit different to the one above: http://www.mtggoldfish.com/archetype/10352 Basically, more card advantage and bigger dudes, less weenie aggro.
