Guild land

Guild lands are nonbasic lands associated with the 10 Ravnican guilds. As of the Return to Ravnica block, there are four types of guild lands.

Cycle name	Azorius	Boros	Dimir	Golgari	Gruul	Izzet	Orzhov	Rakdos	Selesnya	Simic
Bounce lands	Azorius Chancery	Boros Garrison	Dimir Aqueduct	Golgari Rot Farm	Gruul Turf	Izzet Boilerworks	Orzhov Basilica	Rakdos Carnarium	Selesnya Sanctuary	Simic Growth Chamber
	When each of these common nonbasic dual lands enters the battlefield tapped, its controller returns a land they control to its owner's hand. Each of these lands can tap to produce two mana, one of each of the its associate guild's colors. Each card's artwork was illustrated by John Avon.
Gates	Azorius Guildgate	Boros Guildgate	Dimir Guildgate	Golgari Guildgate	Gruul Guildgate	Izzet Guildgate	Orzhov Guildgate	Rakdos Guildgate	Selesnya Guildgate	Simic Guildgate
	Each of these common nonbasic lands with the Gate subtype enter the battlefield tapped and produce one of either of its respective guild's colors. In light of the Ravnica block bounce lands being too "good" in Limited but the necessity for common mana-fixing, these lands were designed. Each of these were reprinted with zoomed-out art and new flavor text in Dragon's Maze.

	Each of these uncommon nonbasic lands taps for and has an activated ability costing mana of the associated guild's colors for a thematically related effect. Each card represents its the associated guild's headquarters within Ravnica.
Shock lands	Hallowed Fountain	Sacred Foundry	Watery Grave	Overgrown Tomb	Stomping Ground	Steam Vents	Godless Shrine	Blood Crypt	Temple Garden	Breeding Pool
	Each of these rare nonbasic dual lands has two basic land types and enter the battlefield tapped unless its controller pays 2 life. Each card's artwork was illustrated by Rob Alexander in the original Ravnica block. They all got new art in the Return to Ravnica block.
