Limited Infinity is a format from the early 2000's, created by Paul Mastriano.
This stack of cards is designed to be drafted among however many players you have, then played either head-to-head, or in a multiplayer game.
The very simple rules:
My playgroup always plays with an additional rule, but it's still fun without it:
The original decklist is in the link at the beginning of this primer, but it only has 230ish cards.
I calculated the ratios to an increase to 500 cards total, and removed all of the tutors (because people who aren't familiar with the cards will slow the game down DRASTICALLY when searching and reading every card).
Try it out and let me know what you think!
