Krosan Restorer 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
: Untap target land. Threshold —
Complete guide
Krosan Restorer is a versatile Human Druid that scales in power as your graveyard fills up. While it starts as a simple way to reuse a single land, it becomes a massive mana engine once you achieve Threshold.
Natural Restoration
The primary function of Krosan Restorer is its activated ability to untap lands. Without Threshold, you can tap it to untap one target land. However, if you have seven or more cards in your graveyard, the Threshold ability unlocks, allowing you to untap up to three target lands with a single tap. Note that these are not mana abilities; they use the stack and can be countered or responded to.
Resolution Step-by-Step
First, you must check if you have seven cards in your graveyard to use the Threshold version. You activate the ability by tapping Krosan Restorer and choosing your targets. When the ability resolves, the chosen lands transition from tapped to untapped status. Because this uses the stack, you cannot activate it in the middle of casting a spell to pay costs; you must generate the mana beforehand by tapping the lands, untapping them with the Restorer, and then tapping them again.
Common Pitfalls
A frequent mistake is assuming the Threshold check only happens upon activation. If you activate the Threshold ability and your graveyard count drops below seven before resolution (due to an opponent's spell), the ability still resolves as long as it was legally activated. Also, remember that since these are not mana abilities, you must pass priority after activating them, giving opponents a chance to respond before your lands actually untap.
Optimal Timing
The best time to use Krosan Restorer is during your main phase to maximize your available mana for large spells, or during an opponent's end step to untap utility lands or defensive mana. In decks that self-mill or discard, getting the Restorer online early allows for explosive mid-game turns where you effectively triple your mana output from your best lands.
Interaction examples
Solemn SimulacrumWhen Solemn Simulacrum enters the battlefield, you search for a basic land and put it onto the battlefield tapped. Krosan Restorer can immediately tap to untap that new land, allowing you to use the mana from that land on the very same turn.
Sakura-Tribe ElderIf you have six cards in your graveyard, you can sacrifice Sakura-Tribe Elder to search for a land. As the Elder moves to the graveyard, your count hits seven, enabling Krosan Restorer's Threshold ability. You can then tap the Restorer to untap the land you just fetched plus two other lands.

How it works : Krosan Restorer
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
Krosan Restorer’s activated abilities aren’t mana abilities. They each use the stack and can be responded to. Notably, they can’t be activated while you’re casting a spell or activating another ability. If you want to use Krosan Restorer to add enough mana to pay for a spell or ability, you may tap land(s) you control, untap them with Krosan Restorer, and tap the lands again all before you start casting a spell or activating an ability.
