If you ever feel like the world has forgotten you, remember it could be worse.

You could be the fourth land in Urza Tron.

What if all the land types were basic?

How does Alpine Moon interact with Tron lands? It is my understanding that naming one of them (Urza's Tower) will shut them all down as it loses its land type and that is what they check against. My friends insist That it will only shut down the one I name as it doesn't change the name of the card and that is what they check. Gatherer has no information on this interaction. Can you point me in the direction of which rules apply here?

Alpine Moon will remove the named land's subtypes and abilities. In the case of the Tron lands, this means that none of them can be tapped for multiple mana because their mana abilities check the subtypes of other lands you control.If you look at the Oracle text of these cards, you'll notice that there's a hyphen in Power-Plant both on the type line of Urza's Power Plant and in the abilities of the other two cards, but not in the name of Urza's Power Plant. This is your clue that you're looking at subtypes rather than card names, as a subtype must be a single word (in English at least), leading to hyphenated subtypes such as Power-Plant and Assembly-Worker. The Tron lands each have two subtypes: Urza's and Mine, Power-Plant, or Tower.If the Tron lands were going to look at names, the ability would be worded "If you control a land named Urza's Power Plant and a land named Urza's Tower, ..." rather than just listing the subtypes, which indicates that you're looking for permanents with those subtypes

When you control a tower, a mine, and a power plant.
