If I play Urborg, Tomb of Yawgmoth after Blood Moon?

Asked by Kjartan 8 years ago

Will lands also be Swamps?

No. Regardless of which order they are played in, Blood Moon(since it doesnt have the phrase "in addition to its other types") will make Urborg, Tomb of Yawgmoth a Mountain, so it will not have a static ability to make your lands swamps as well.

And there is no overwright as with Godhead of Awe followed by Biomass Mutation?

@Dracoson - This is actually not the case. Because of timestamp ordering, all non-basic lands will be Mountains and Swamps. Urborg, Tomb of Yawgmoth will not have its ability but will still be a Swamp in addition to its other types. If you look at the layers system, typesetting (layer 4) comes before ability removal (layer 6).

This is on Oracle.

4/1/2008 If Urborg, Tomb of Yawgmoth and either Blood Moon or Magus of the Moon are on the battlefield, 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.

@Kjartan - There would be an override of sorts in your Godhead example. Assuming the Biomass Mutation was cast after the Godhead, your creatures would be X/X until end of turn. Here is a good link for the layering system.

@nobu_the_bard - I REAALLLY need to start checking Gatherer before answering questions. This is the second time today that I made this kind of mistake.

merrowMania - I get it now, having a better undertstanding of the layer system will be a great advantage when it comes to complex interactions in future games.

merrowMania - However, since Blood Moon is still active, why won't in remove Urborgs effect when layer 6 applies?

Happy to be of help, but I'm not sure if I got the correct answer for the Urborg/Blood Moon question. Though the Oracle does not provide actual steadfast rules, it is usually reliable enough to be considered as such. My answer was based on the interaction between a Blood Moon followed by a Prismatic Omen and Yixlid Jailer vs. a Mistform Ultimus in a graveyard.

Ah, there it is XD, I've gotten way too used, to be in need of rules so frinch that gatherer has no answers.

There is an explanation about the interaction between Blood Moon and Urborg, Tomb of Yawgmoth farther down in the article. It provides an in-depth explanation about why the Oracle entry is correct and I was mistaken.

Answer reselected to one that addresses the question in the original post.

In short, the reason this works the way it does is that Urborg, Tomb of Yawgmoth has what's called a "dependent ability." Because Urborg's ability can't apply at all if Blood Moon's ability is applied first, Urborg's ability is said to be dependent. Moon's ability applies and overwrites Urborg's ability, which can then no longer apply.

To answer the layer questions that came up earlier: Blood Moon doesn't operate in layer 6 (ability adding/removing). It operates in layer 4 (type changing), just like Urborg, Tomb of Yawgmoth. Because the effects are in the same layer and Urborg is dependent on Blood Moon, Blood Moon is applied first.

Rhadamanthus - Yes, but won't the ability of urborg then first be removed when layer 6 comes around?

February 5, 2016 11:38 a.m.

Nothing here is applying in layer 6. The effects involved change cards' types. Because the five basic mana abilities are tied to the five basic land types, gaining or losing a type has an implicit effect on those abilities. This does not constitute a layer 6 effect. The type changing happens in layer 4.

Rhadamanthus says... #16

No, because the abilities are gone as soon as the type changes. The ability isn't being removed by a continuous effect operating in layer 6. Rather, it's being removed by a game rule regarding basic land types:

305.7. If an effect sets a land's subtype to one or more of the basic land types, the land no longer has its old land type. It loses all abilities generated from its rules text, its old land types, and any copy effects affecting that land, and it gains the appropriate mana ability for each new basic land type...
