Mountain Valley is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
This land enters tapped., Sacrifice this land: Search your library for a Mountain or Forest card, put it onto the battlefield, then shuffle.
Complete guide
Mountain Valley is a classic 'slow fetch land' originally from the Mirage expansion. It provides budget-friendly mana fixing by allowing you to search for specific basic land types from your library. Because it enters the battlefield tapped, it requires careful planning to maximize your turn-by-turn efficiency.
A Gateway to Mountains and Forests
The primary function of Mountain Valley is to thin your deck and ensure you have the correct colors of mana. When you activate its ability by tapping and sacrificing it, you search your library for a card with the Mountain or Forest subtype. This is not limited to basic lands; any land card that explicitly lists 'Mountain' or 'Forest' on its type line can be retrieved.
Step-by-Step Resolution
First, Mountain Valley enters the battlefield tapped, meaning you cannot use it the turn you play it. On a subsequent turn, you pay the cost: tap the land and sacrifice it to the graveyard. This puts the activated ability on the stack. When the ability resolves, you search your library for a Mountain or Forest card and put it onto the battlefield. Finally, you must shuffle your library, regardless of whether you found a card or not.
Strategic Timing and Constraints
One common mistake is forgetting that you don't actually have to find a card. If you realize your library no longer contains a Mountain or Forest, you still complete the action of searching and shuffling. Additionally, remember that the land you fetch enters the battlefield untapped unless that specific land card has its own rule stating otherwise. This allows you to use the new mana source immediately upon resolution.
When to Play Mountain Valley
This land is best played on early turns where you don't have a proactive one-mana play, or on turns where you have excess mana and can afford the temporary loss of a land drop. It is also an excellent tool for triggering 'Landfall' abilities or clearing the top of your library after using effects that manipulate your deck's order.
Interaction examples
You play Mountain Valley as your land for the turn. It enters tapped. On your next turn, during your opponent's end step, you tap and sacrifice it to search for a basic Mountain. The Mountain enters the battlefield untapped, and you start your own turn with a fresh red mana source ready to go.
If you have a non-basic land in your library that is both a Forest and a Plain, Mountain Valley can find it because it checks for the 'Forest' subtype. You sacrifice Mountain Valley, search for that specific dual-typed card, put it onto the battlefield, and then shuffle your library.
Suppose all your Mountains and Forests are already in play or in your graveyard. You can still activate Mountain Valley to trigger a shuffle. You look through your library, find nothing (as allowed by the rulings), and then shuffle. This is useful if you know the card on top of your deck is not what you need.
