Magic: The Gathering Arena’s Gladiator Community Event announced - Date, rewards, and more

sportskeeda.com:

Wizards of the Coast announced an upcoming community event for Magic: The Gathering Arena, with an interesting format. Gladiator is coming soon as a limited-time event for the digital version of MTG, and it will feel familiar to Singleton and Commander fans while certainly being its own casual format.

The next big community event is coming soon, and while it’s unclear if Magic: The Gathering Arena will return to Gladiator or keep it around as a format, the event is coming next week, and here’s what fans need to know about it.

Gladiator is a casual Magic: The Gathering format and is essentially an extension of Singleton. This particular format began as a way to play Magic: The Gathering Arena in a new way in tabletop arrangements, adding a little bit of extra deckbuilding challenges and helping casual players that lack huge collections of cards.

Players need to have a deck of at least 100 cards to play Gladiator, and they can only use each card once. There are exceptions, of course. Basic Lands can be used without limit, as can cards that state players can use them unlimited times.

Gladiator is typically played in a best-of-three format and does not allow a sideboard. It’s a format where players can build practically whatever style of deck and compete. This particular format is coming to Magic: The Gathering next week.

In casual, tabletop MTG, there are no banned cards other than what a group of friends agree upon. In this event, all cards in their original format (so no Alchemy cards) are permitted in decks, with some exceptions.

A small list of cards known to break the game, or feel unfun/overpowered, will be banned from the event. It's not a lengthy list, but it’s essential to be aware of.

As in many Magic: The Gathering
