Pretty much a tri-land. It sets you back a land, but it comes into play untapped...and, as the oracle says, you can tap it in response to sacrificing it. Thus, it could also be seen as a 1-time source for three mana. Not bad, I'd say. 4/5, at least, for me.

An uncommon use of Lair lands like this is in a landfall deck to return lands to your hand for the purpose of replaying them. This is especially useful in tandem with cards that allow you to play additional lands in a turn, like Oracle of Mul Daya or Azusa, Lost but Seeking. You can also use it to replay lands that give you a benefit when they come enter the battlefield, such as Khalni Garden or Sejiri Refuge and other refuge cards. Lastly, you can use Lairs to renew counters on land cards that come into play with counters on them, like Vivid Grove or Llanowar Reborn.

the card doesnt say untaped land so i tap the land for mana before i use it. i use ot in my sliver deck to bounce my gemstone mine back up to my hand when i use its second to last counter

Rather overlooked in my opinion, and this goes for the entire lair series. I've found it most useful in EDH, where mana-fixing on a budget can be quite difficult.

Cheap, does it's job well and can set up a few rudimentary combos, 4/5.

Landfall and lands with comes-into-play effects combo with all the Lairs, and they are additional mana fixers in EDH.
