Legendary land

Legendary lands were first introduced in Legends. Despite the drawback many of them were banned from various formats. 
==Legendary land cycles==
===Legends===
The first cycle of legendary utility lands is from Legends. Each land produces mana of the associated color, and has an activated ability which can be activated by tapping.

*<c>Urborg</c> () 
*<c>Hammerheim</c> () 
*<c>Pendelhaven</c> ()

*<c>Tolarian Academy</c> () 
*<c>Phyrexian Tower</c> () 
*<c>Shivan Gorge</c> () 
*<c>Gaea's Cradle</c> ()
===Weatherlight Saga===
A mega-megacycle of legendary lands representing important locations of the Weatherlight Saga. All of them are utility lands with the exception of <c>Teferi's Isle</c>, which is a phasing tapland that produces .
One land was printed in each of the five blocks that make up the saga: Mirage block, Tempest block, Urza block, Masques block and Invasion block.

===Champions of Kamigawa===
Another cycle of legendary utility lands was printed in Champions of Kamigawa. They work like the ones from Legends, but requires one colored mana in addition to being tapped.
*<c>Eiganjo Castle</c> ()
*<c>Minamo, School at Water's Edge</c> () 
*<c>Shizo, Death's Storehouse</c> () 
*<c>Shinka, the Bloodsoaked Keep</c> () 
*<c>Okina, Temple to the Grandfathers</c> () 
===Time Spiral===
A megacycle printed across the first two sets of the block (Time Spiral and Planar Chaos). The fifth card of the cycle is a timeshifted card from Legends: <c>Pendelhaven</c> is, therefore, part of two different legendary lands cycles.
*<c>Flagstones of Trokair</c> () from Time Spiral A fetch land for Plains.
*<c>Academy Ruins</c> () from Time Spiral.
*<c>Urborg, Tomb of Yawgmoth</c> () from Planar Chaos

*<c>Pendelhaven</c> () from Time Spiral/Timeshifted.

**<c>Gemstone Caverns</c> can be seen as the sixth part of the cycle producing either colorless mana or mana of any color (depending on luck).
===Ixalan===
Ixalan introduced a cycle of lands which transform from legendary enchantments. In general, the lands may be tapped for one mana of their respective color. They are all utility lands, with the exception of <c>Itlimoc, Cradle of the Sun</c>, whose alternate ability is to tap for equal to the number of creatures under its owner's control.

===Rivals of Ixalan===
Rivals of Ixalan introduced a cycle of lands that transform from enemy color legendary enchantments. In general, the lands may be tapped for one mana of any color. They are all utility lands, with the exception of <c>Vault of Catlacan</c>, whose alternate ability is to tap for equal to the number of artifacts under its owner's control.
