Locus

Locus is a nonbasic land type used for cards that depict mana rich observing posts on Mirrodin. 
==Description==
The first card to bear the type was <c>Cloudpost</c> in Mirrodin. It adds for each Locus on the battlefield. Because multiple Loci looked inherently broken, R&D was hesitant to create additional ones. Each new Locus would increase the amount of mana generated by Cloudpost. However, with the printing of <c>Glimmerpost</c> in Scars of Mirrodin deckbuilders were gifted a second playset of Loci and, alongside the landcopying <c>Vesuva</c> from Time Spiral could play up to twelve in one deck. While fine for the Extended format, <c>Cloudpost</c> ended up on the Modern banlist on the second round in September 2015, and has stayed there since.
Phyrexia: All Will Be One contained <c>Monument to Perfection</c>, a card that can search for a Locus, but didn't add any new Locus cards. However, MH3 Commander added the third Locus with <c>Trenchpost</c>, and also featured <c>Planar Nexus</c>, which is every non-basic land type.
===Storyline===
Created by Memnarch to observe his imported creatures, they were later taken over by the Praetors of New Phyrexia. 
===Trivia===
*Locus is a land type, not a creature type; changelings are not a Locus and you can't use <c>Conspiracy</c> to make a creature a locus.
**To deliberatly confuse the issue, Locus was used as a creature type on the Mystery Booster test card <c>Swarm of Locus</c>.
*Locus is also a location on Otaria, created by Ixidor
*<c>Planar Nexus</c> has the type from its ability to have all non-basic land types.
