Experienced Niv Mizzet (EDH / Commander)

Reworked with Sisay as the commander: https://deckstats.net/decks/148635/1572239-experienced-sisay/en
It moved into the right direction but was still too convoluted.
Scraping and building an Atraxa deck.

Introducing the Experienced Niv Mizzet.
Using the 5 Experienced based legends, the idea is to create 5 unique but supportive paths to victory.
The goal is to build up experience as fast as possible, creating tokens along the way, buffing, and skyrocket off with massive amounts of reusable value.

Inspired by 18ths: http://tappedout.net/mtg-decks/five-mizzet-re-experienced/

"Ezuri, Claw of Progress - easily the best one out of the five in this deck. Requires very little setup, generates tons of experience and makes very good use of them. He can pump the creatures to enormous sizes, so cards giving evasion should be good to maximize this.
Best friends: Fathom Mage, Elenda, the Dusk Rose, Hero of Precinct One, Twilight Drover

Meren of Clan Nel Toth - the dreaded one and for good reason. Similarly, requires little setup - some sacrifice engines are needed, but if you have them, Meren is an almost infinite engine of experience - sac the token maker, bring it back making tokens while entering the battlefield, rinse and repeat. When you have plenty of them she's still very valuable - to the point I expect she will be heavily targeted, so you probably need some backup graveyard recursion.
Best friends: Spawning Pit, Avenger of Zendikar, Teysa, Orzhov Scion

Daxos the Returned - Not very helpful at gaining counters (although it might happen), but can be crazy good later - imagine repeatably getting (at least) 5/5s for 3 mana at instant speed. As those tokens will grow as the game progresses - evasion is also needed.
Best friends: Cryptolith Rite, Nylea, God of the Hunt, Rhythm of the Wild

Mizzix of the Izmagnus - A bit similar to Daxos - quite bad at gaining counters (although a bit better than him), but can be much better later. His synergy with X spells is crazy and there are many more instants and sorceries good at making tokens than enchantments.
Best friends: Curse of the Swine, Sphinx's Revelation, March of the Multitudes, Finale of Eternity, Secure the Wastes

Kalemne, Disciple of Iroas - the worst one, but if stars align, can one-shot a player with a bit of evasion. It has some synergy with Theros gods and Daxos, as they are both big and enchantments, so it's also possible to generate experience. It also helps that our commander is a 6/6 and there are some bigger guys in the deck.
Best friends: Iroas, God of Victory, Pollenbright Wings, Nylea, God of the Hunt, Rhythm of the Wild, Jhoira of the Ghitu" - 18ths
