Ixtol, Champion of Endra

Based off of fellow Team Not-Tavrod member AGhostlyToaster's extremely popular Praxis deck, Ixtol, Champion of Endra has come about kind of by chance. I wanted to try the new Ixtol, Champion of Grodov and stumbled upon a quite effective counter to Endra decks.
Keys to its success come in Sandstorm Titan to fight Haunting Scream tactics, Tocas, Waystone Harvester to counter copy, sacrifice, and combat tricks. Yushkov, the Usurper plays double duty in countering scream effects and ramp to get early threats out. Ixtol, Champion of Grodov is just stupid when you drop Kairos, Grand Champion or the other way around, dropping an Ixtol when you have Kairos on board to do an insane amount of damage.
The market includes Lumen Reclaimer which is key to disrupting the Endra, Champion of Shavka chain. Porcelain Mask makes blocking inconsequential with Kairos and Ixtol on board.
Flex spots are 2x Moondial. You can put whatever you like in this spot. I like the guaranteed one card draw and usually more, especially late in the game with a usual Praxis top deck mode.
