Memnarch

[Balefire Hellkite]

{Memnarch} is colorless, but his ability requires {U} mana. So as a commander, is Memnarch colorless or blue?

[LinkCelestrial]

He is blue. Just like {Tasigur, the Golden Fang} is Sultai.

Think about it, if your commanders colour identity is colourless you can't produce blue mana so his ability is useless!

Wait what? Tasigur colorless?

Yeah, he's black

But I'm perfectly sober and not high. I'll blame it on lack of sleep.

Also you couldn't use basic land, in colorless EDH

Wait, you can have any basic land in the deck, it just produces colorless, right? Is that what you were saying?

In colourless decks like {Karn, Silver Golem} and {Kozilek, Butcher of Truth}, you can't have any basic lands in your deck since they have mana symbols that your commander doesn't.

In a colorless edh deck, you cannot run basic lands. Even though they are colorless per game rules, their color identity is whatever color they produce

[Wingnut]

Looked at some rulings, I was wrong. Nothing to see here folks, keep moving.

903.5d A card with a basic land type may be included in a Commander deck only if each color of mana it could produce is included in the commander's color identity.

I found this while trying to explain to a monored player, who wanted to use {Gem of Becoming} and run a single swamp and islisland for mana acceleration.

I read in a different EDH topic that there is a leniency rule for colorless commanders, else you would need a LOT of different generic mana lands. I'll see if I can find it.

[Prplprince]

Lands are colorless so if you could put in different lands of colors your commander isn't you could technically run all 10 orig duel lands and 10 shock lands etc etc.
