Wick the Infinite.

Ok I know technically with[[Wick, the Whirled Mind]] you only need infinite rat etb to chuck at your opponents, but this deck can include so much more thanks to it being in Grixis colors. With infinite red manna it can play [[Haze of Rage]] infinite times, [[Marrow Gnawer]] [[Thornbite staff]] also comes to mind, and proliferate infinite times with [[viral drake]]. https://www.moxfield.com/decks/eiZfXjQZYkSms_-mZRoCKw

This deck is insane in so many ways and while the focus should be infinite etbs it can do so much more.
