Domain Zoo has randomly been a mildly competitive pauper deck over the years, most of the time it's not. The masters sets over the past couple years have been really good for the archetype (basically anything is an improvement over having to run skred), giving us access to both Kird Ape and Burning-Tree Emissary. The unique composition allows us to play a bunch of powerful cards from every colour.
We run 20 very powerful creatures in the list.
Kor Skyfisher - we run like 8 cantrip enchantments which makes the downside bearable and the evasive body is sweet.
Burning-Tree Emissary - Great creature that leads to powerful tempo turns, generally a great addition to the deck.
Mancta Rioters - probably the biggest reason to make this a domain list, 5/5s for 3 are sweet and nothing is going to change that.
Kird ape - Beautiful kird ape making this deck less of a complete waste of money i honestly think another good threat was what the deck was missing so i have high hopes in this little guy.
Wild Nacatal - literally the best zoo card 1 mana 3/3s are even better than 3 mana 5/5s great card 10/10.
Having access to 5 colours fairly consistently allows us to play some pretty powerful spells
Brainstorm - This card is good i don't have to tell you that, we do have to be light on blue sadly so this is kept as a 2 of.
Unearth - same thing as Brainstorm, card is really good but it's in our off colour so we have to be careful with it.
Lightning Bolt - card is too good to pass up, it's in our main colours and does almost everything the deck needs.
Tribal flames - this can kill anything the mono black control list plays for 2 mana, that alone is good enough to make the cut. The card is just insane in the deck in general 2 mana deal 4-5 is always going to be good and burning someone out from 20 for 8 mana is pretty gross.
Abundant Growth - cantrip and mana fixing super good, super important.
Nylea's Presence - honestly this is the only reason the deck can work, this enables all of our basic requirements and fixes our mana what else could you want?
Obviously side boards are going to highly depend on what you're playing with, but this is the side I'd feel most comfortable bringing to a pauper league on MTGO seeing as it's the biggest stage pauper has at the moment.
Ancient Grudge - Really good against any of the artifacts matter decks (metalcraft/kitty/kuldotha) because it can mess up their combat math and other things important to that deck.
Electrickery - I didn't want to run into any jank decks that would beat me if i didn't have a way to kill 1/1s so Electrickery finds its way into the deck.
Qasali Pridemage - solid threat if we need to side in more creatures, good against boggles and such.
Pyroblast - With drake banned blue is still a powerful colour because of delver and other blue based decks.
Ray of Revelation - Bogles is good now so i need a way to interact with enchantments.
Relic of Progenitus - shoutout to TTC and G/B Dredge that deck is sick and i don't want to lose to it.
