Lord Commander is a format where each player uses a "Lord" creature as a commander similar to edh, however there are some extra rules and conditions that are very different to traditional commander. 

Below the rules are every Lord Commander that can be played in this format as of writing. The rules and legal Lord Commanders will be updated every time I post a new LC deck, I know no one really plays this format but I'm thinking of making somekind of website for anyone who might find it interesting. 

Lord Commander Rules:

No Legendary Creatures can be Lord Commanders, but you may put Legendary Creatures in your deck. 

A Lord Commanders must have an ability that grants all creatures of a particular or general type an effect, these effects generally include the words Each/All and Gain/Have/Get. This effect must be persistent, creatures with enter the battlefield "Lord" effects are not included in this format, nor are creatures that require an ability to be activated for the effect to happen, however creatures that trigger an effect by attacking are included as legal Lord Commanders. Creatures with abilities that say "as long as" conditionally for the lord effect are excluded from this format, as are Lord creatures that must attack individually by themselves for the lord effect to occur. 

Like a traditional commander, your Lord Commander begins the game a Command Zone. All usual rules for this zone apply, however commander tax is 1 mana instead of 2 mana. 

Each deck must contain 80 cards including your Lord Commander. 

Every non-silver bordered, non-acorn, non-unset creature card is legal in this format. 

Each creature in your deck must share a type with your Lord Commander or must be specifically mentioned as a part of that lord's effects, creatures that do not share a type with your commander cannot be in your deck, this rule does not apply to tokens. 

Sagas, Battles, and any other card types that flip into creatures are subject to the Lord Commander type restriction, for example, if you play Life of Toshiro Umezawa // Memory of Toshiro your Lord Commander must have Samurai or Human in its type for you to legally include this card in your deck.

Excepting basic lands, no two cards may have the same name in your deck, unless an effect on them states otherwise.

Cards in your deck must also share at least one colour with your Lord Commander, if a Lord’s effect or colour identity does not give you access to multi-colour then you cannot have multi-colour cards in your deck. Multi-colour Lord Commanders can have any multi-colour cards in their deck, but those cards must share a colour with the Lord commander, otherwise they cannot be played in the deck, this rule applies to lands as well. Any deck may contain colourless cards. Non-creature cards and Lands must also adhere to this colour identity rule.

A deck may have multi-coloured cards in it if their Lord Effect directly relates to multi-coloured creatures, however, each multi-colour creature must share a colour with you Lord Commander to be legal in a deck. Non-creature cards must also adhere to this rule.

Any ability on a Lord Commander that requires or provides multiple colours, including effects like Extort, determine the colour identity of that Lord to be of those required/provided colours.

Players begin the game with 30 life.

Players may have a Wishboard of 3 Cards that exist outside the game but can be targeted by relevant effects, these cards must adhere to all previous rules. 

Legal Lord Commanders:

- Each Sliver is a legal Lord Commander, excepting Essence Sliver, Diffusion Sliver, Brood Sliver, and Metallic Sliver. 

*~* - Each of the creatures marked this way is a multi-colour Lord Commander but their core colour is represented on their card.
