Oathbreaker

Oathbreaker is a casual, multiplayer, singleton format. It is a variant of Commander, though its creators object to referring to it as such. In March 2023, the format was officially recognized by Wizards of the Coast, though there were no dedicated products planned.
==Description==
Rather than choosing a legendary creature as a commander, players select a planeswalker as their Oathbreaker, and an instant or sorcery as that Oathbreaker's Signature Spell. The Oathbreaker follows rules identical to those for commanders governing starting the game, the additional cost for each additional cast, and changing zones. The Signature Spell is subject to similar rules, but with two additional restrictions: It can only be cast while its owner's Oathbreaker is on the battlefield, and it always returns to the command zone upon resolution, overriding all other effects and rules, breaking the functionality of some abilities, such as buyback.
As in Commander, the Oathbreaker's color identity restricts deck construction to cards within that color identity, and no two cards may share a name, with the exception of basic lands. Cards that refer to "your commander" instead refer to "your Oathbreaker".
Unlike Commander, Oathbreaker decks must contain exactly 60 cards (including the Oathbreaker and Signature Spell). Players start at 20 life, and the Oathbreaker format does not include commander damage (see rule 903.10a) as a win condition.
A banned list is maintained by the format's creators.
