Yes, Blood Moon is a subtype-changing effect, which means it will replace the land types (which, by definition, are subtypes which lands can have) with Mountain. It will also remove all abilities the land had before. However, Artifact is neither a subtype nor an ability, it is a regular type, so the Blood Moon won't touch it.
It doesn't matter which order they come into play.
Quote from Autocard du jour »
01/04/2008 If Urborg, Tomb of Yawgmoth and either Blood Moon or Magus of the Moon are in play, all nonbasic lands will be Mountains, not Swamps. Urborg, Tomb of Yawgmoth will be a Mountain as well. It will have "{T}: Add R to your mana pool" and no other abilities.
MajoraX is correct. The reason for that is dependencies. Both effects are type-changing effects, so they are both applied in Layer 4. Now applying the Blood Moon's effect will remove the Urborg's ability entirely, so it most certainly changes the ability or what it applies to. Therefore, Urborg's ability is dependent on Blood Moon's (but, importantly, not vice versa since Urborg doesn't change what is and isn't a basic land), so we apply Blood Moon's ability first.
The result is that Urborg no longer has an ability to apply, it will simply sit there and tap for :symr:. Note that this means basic lands won't get the swamp subtype (where they would have if we'd applied the abilities in the other order).
You will choose a land for Vesuva to copy - However, all lands are mountains so it won't really matter (unless you wanted to gain some type by copying an Artifact Land)
City of Traitors lost its triggered ability when it became a mountain. You won't have to worry about it.
Llanowar Reborn will come into play with a +1/+1 counter on it, but you won't be able to transfer it.
New Benalia will lose its trigger.
The important thing to remember here is that "as ~ comes into play" abilities replace coming into play normally with something else (like coming into play tapped). They aren't affected by Blood Moon because they aren't in play yet. "When ~ comes into play" abilities won't trigger, because they trigger from play - but the ability doesn't exist.
Cards in MTG only do what they say they do, no more no less. Blood moon only changes the cards subtype to Mountain and in doing so remove all rules text and add t : add R to your mana pool.
Since it does not mention adding supertypes or changing card types it doesn't effect them.

I don't care if I was framed for murder if I only got a warning I would let it go.
Will it makes a difference if blood moon hits play first or Urborg hits play first?
This one always confuses me. Thanks!

Note that Llanowar and Benalia have both a triggered and a replacement ability. The replacement applies but not the triggered.
Triggered abilities always start with "when" "whenever" or "at."
Does Blood Moon change the type of land from say non-basic to basic? Someone told me it doesn't and I want to make sure of it.
Please let dead threads rest in peace. This should've been a new thread. -Carsten
