Gathering Stone — ruling 1

You don't have to reveal the card you look at with Gathering Stone's third ability even if it's a card of the chosen type. If you choose not to reveal it this way, you can still put it into your graveyard.

Gathering Stone — ruling 2

Gathering Stone's second ability applies only to generic mana in the total cost of spells you cast of the chosen type.

Gathering Stone — ruling 3

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of this ability). The mana value of the spell is determined by only its mana cost, no matter what the total cost to cast that spell was.

Gathering Stone : règles, fonctionnement et interactions (MTG)

Gathering Stone 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

As this artifact enters, choose a creature type. Spells you cast of the chosen type cost less to cast. When this artifact enters and at the beginning of your upkeep, look at the top card of your library. If it's a card of the chosen type, you may reveal it and put it into your hand. If you don't put the card into your hand, you may put it into your graveyard.

Complete guide

Gathering Stone is a versatile artifact designed to bolster your tribal strategies by smoothing out your mana curve and providing consistent card advantage. By selecting a specific creature type, you turn this ancient relic into a beacon for your allies, helping them reach the battlefield faster and more frequently. It is an essential tool for any deck focused on a unified army of creatures.

Choosing Your Path

As Gathering Stone enters the battlefield, you must choose a creature type like 'Golem' or 'Human'. This choice is not a triggered ability and does not use the stack, meaning opponents cannot react to the choice itself once the artifact begins to resolve. This choice determines which spells will receive a cost reduction and which cards you can draw during your upkeep.

Filtering the Library

The third ability triggers both when Gathering Stone enters and at the start of your upkeep. You look at the top card of your library; if it matches your chosen type, you may reveal it to add it to your hand. If the card isn't the right type, or if you simply don't want to reveal it, you have the option to move that card to your graveyard, effectively 'scrying' through your deck to find better draws.

Cost Reduction Mechanics

The cost reduction applies to the total cost of the spell, which includes additional costs like Kicker or commander tax. However, it only reduces generic mana requirements. It does not change the mana value of the spell, nor does it affect colored mana symbols in the cost. If you cast a spell that costs only one generic mana, it will cost zero to cast.

Strategic Timing

Gathering Stone is most effective when played early to maximize the mana savings over several turns. Because it triggers on your upkeep, it provides a 'draw' effect before your normal draw step, allowing you to build momentum. It also serves as a graveyard enabler, helping you dump specific cards if you have ways to recur them later.

Interaction examples

Efficient Golem Deployment

Solemn Simulacrum

If you chose 'Golem' for Gathering Stone, the total cost to cast Solemn Simulacrum is reduced from {4} to {3}. When Gathering Stone enters, if Solemn Simulacrum is on top of your library, you can reveal it to put it into your hand, then immediately cast it for the discounted price to search for a land.

Managing Your Top Deck

Commander's Sphere

During your upkeep, you look at the top card of your library and see Commander's Sphere. Since it is an Artifact and not a creature of the chosen type, you cannot put it into your hand using the Stone's ability. However, you may choose to put it into your graveyard, effectively clearing the way so your normal draw for the turn is a new, unknown card.
