Atraxa Poison Bullshit (EDH / Commander)

Just your terrible Atraxa deck, it uses every opportunity to put poison counters on your opponents, with the awful new spells from Phyrexia All Will Be One, such as "Prologue to phyresis", "Infectious Bite", "Vraska's Fall", "Infectious Inquiry" or "Phyresis Outbreak". It also has small toxic or infect hitters.

Once all your opponents have one poison counter, it is time to PROLIFERATE. You have all the tech to do so multiple times, Tekuthal, Inquiry Dominus will double all your proliferate triggers, Brokers Confluence allows you to proliferate 3 times in one spell and close the game pretty fast, your commander will proliferate once a turn as long as she survives the inevitable focus. You can now TURBO PROLIFERATE thanks to the recently added Inexorable Tide, the low manacurve make this one really brutal.

I also put some weird little shenanigans like Ezuri Claw of Progress which will allow your small creatures with infect to grow very big and Lurrus of the dream den to play them again and again, also the Agent's Toolkit will permit you to put good counters without depleting thanks to the proliferation, and norn's Wellspring and Tome of Legends are draw engines that will skip their condition to put the counters on, most of the time.

The landbase is honestly piss poor but was made to be pretty : All the painlands and bouncelands are full arts. It also includes Mirrodin's Core, the vivid lands, Tendo Ice Bridge and Gemstone Mine because proliferating makes it more viable.

The brand new dreamtide whale is a very cool way to block your opponents from fast playing while rewarding you casting twice a turn, and she is borderline impossible to lose to Vanishing thanks to your other proliferation sources.
