Almost no cost mana fix. This card is perfect in any deck with more than one color.

I never liked this or chrome mox drawback. Ive never been a tourney player either.
I guess its great with 
card draw, to replace the lost cards and still be ahead of your opponent.

Immensely less powerful than the original version, which could be tapped for mana before you had to sacrifice it, making it basically the same thing as Lotus Petal in that instance, this card is still ridiculously good.
In any multicolored deck, this becomes mana ramp plus color-fixing, if you discard a land you already have in play.
4.5/5

Weird and confusing wording. Should have read something like:
"When Mox Diamond enters the battlefield, discard a land card. If you don't, sacrifice Mox Diamond."
or
"As an additional cost, discard a land card."
Besides that, great card! A classic.

It's to catch people who try and cheat it into play and to force the player to discard the land to get any value out of the mox.
I believe the first wording would allow the player to still tap the mox for mana as a response to the trigger.
The second wording would not force the player to discard a land if it could be not hardcasted (e.g. tinker. of course you wouldn't tinker this into play, but that's beside the point).
Is it necessary? I don't know, because I don't play legacy or vintage so I wouldn't know how significant it would be to alter the wording. But it's not like this card needs a buff anyway, so whatever.

Free ramp for any color is never a bad thing.

IF I cast march of the machines, does this go into the graveyard?

The guy from Land Tax says, "What card disadvantage?"

The reason it's awkwardly worded is that if it was just "when Mox Diamond comes into play, you may discard a land card. If you don't sacrifice Mox Diamond" you could tap it in response to its etb trigger, still getting mana for it.
