Momir Basic is a Magic the Gathering format where every spell is a random creature from Magic’s collection of cards.
Each player comes to the battle with a 60 card deck of nothing but basic lands and a Momir Vig emblem that reads:
{X} Discard a Card: Create a token that’s a copy of a random creature card with converted mana cost X. Activate this ability only any time you could cast a sorcery and only once each turn.
With nothing but lands in your deck, you play lands, tap for mana and generate a random card.
It’s mainly a digital format on Arena and Online due to it’s randomness feature but some people play it on paper with a help of a receipt printer. Aforementioned Tolarian Community College video and Rhystic Studies’ video on the format are great introductions to the format.
I love these kinds of wacky formats and I’m especially drawn to the idea of building a self-sustained printer + microcontroller device just for the fun of it.
Another idea that tickles my DIY craft-y brain is to use a tool like Momir Basic and a stack of dry erase cards to play a slow game where everyone draws their cards rather than prints them.
