Legacy Land deck
The Land deck, usually just called XX Lands, where XX is the number of lands in the deck, is a deck focused around that card type.
The deck uses Exploration and Manabond to put a large quantity of lands with various effects into play consistently and is able to reuse discarded or destroyed lands with Life from the Loam and Crucible of Worlds. Intuition and Gamble, are easy tutors for the deck as it is generally graveyard based and can profit off the downsides of these tutors.
There are a large variety of lands used in the deck. They may draw cards (Tranquil Thicket, Horizon Canopy), keep the opponent off his or her mana (Wasteland, Rishadan Port), or otherwise disrupt the opponent's game plan (Glacial Chasm, Barbarian Ring, Maze of Ith, The Tabernacle at Pendrell Vale). Others Lazav is The Mimeoplasmprovide support (Maze of Ith, Academy Ruins). The win condition is usually a manland such as Mishra's Factory, Creeping Tar Pit, or Nantuko Monastery. The deck generally runs a fair amount of artifacts, as Academy Ruins is a very powerful engine in the deck. Recently, decklists have avoided red, often running an Enlightened Tutor toolbox.
