Gladiator decks
What is the Gladiator format in Magic?
Gladiator is a community-created Magic Arena singleton format using decks of at least 100 cards. There are no commanders, no sideboards, and players begin with 20 life, with normal matches played best-of-three.
Its card pool consists broadly of cards available on Arena, subject to the Gladiator banned list. Unlike Commander, there are no color-identity restrictions, allowing the format to play more like an enormous singleton Constructed Magic.
