Carte Magic Scrap Mastery

Scrap Mastery 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.

01

Official card text

Each player exiles all artifact cards from their graveyard, then sacrifices all artifacts they control, then puts all cards they exiled this way onto the battlefield.

Complete guide

Scrap Mastery is a powerful red sorcery that acts as a Living Death specifically for artifacts, swapping everything on the board with what is in the graveyard. It is a game-changing effect that can turn a pile of junk into a lethal board state in an instant. This card is a staple for artifact-centric decks looking to recover from a board wipe or execute a massive combo.

What It Does

Scrap Mastery performs a three-step sequence that completely reorganizes the battlefield for all players. First, it clears all artifact cards out of the graveyards into a temporary exile zone. Second, it forces everyone to sacrifice the artifacts they currently have on the battlefield. Finally, it brings the cards that were moved to exile in the first step directly onto the battlefield under their owners' control.

How It Resolves Step by Step

When Scrap Mastery resolves, you follow the instructions in order. First, check all graveyards and move every artifact card there to exile. Next, every player sacrifices all artifacts they currently control; these sacrificed artifacts go to the graveyard (unless a replacement effect says otherwise). Finally, the specific cards that were moved to exile during the first step of this resolution are put onto the battlefield. Note that any artifacts sacrificed in step two remain in the graveyard and do not return.

Common Mistakes

A common point of confusion involves the phrase 'exiled this way.' This only refers to the cards moved from the graveyard to exile during the first part of the spell's resolution. If a replacement effect, such as Rest in Peace, causes your sacrificed artifacts to be exiled instead of going to the graveyard, those artifacts are not considered 'exiled this way' and will not return to the battlefield. Additionally, enter-the-battlefield abilities of the returning artifacts will trigger, but they won't see the artifacts that were just sacrificed.

When to Play It

The best time to cast Scrap Mastery is when your graveyard is filled with high-impact artifact creatures or utility pieces, while your current board is either empty or contains cheap artifacts like Treasure tokens. Because it is a sorcery costing five mana, you will often want to ensure you have enough resources to protect your new board or benefit from the sudden influx of permanents immediately.

Interaction examples

Fueling the Masterwork

If your opponents have many tapped lands, you can cast Mana Geyser to generate a large amount of red mana. Use five of that mana to cast Scrap Mastery, allowing you to bring back massive artifacts from your graveyard even if you haven't built up your own land base yet.

Survival of the Fittest

Imagine you have a large artifact creature on the battlefield and several powerful ones in your graveyard. You can cast Chandra's Ignition to deal damage to the board; if your creature dies or you sacrifice it later, Scrap Mastery can then be played to swap your current board for the artifacts in your graveyard, ensuring you maintain pressure after the board clear.

Recovering from Ruin

If an opponent destroys your board of artifacts, they end up in your graveyard. On your turn, you cast Scrap Mastery. You sacrifice any remaining tokens or utility artifacts, then all those powerful cards that were destroyed are returned to the battlefield at once, completely reversing the opponent's progress.

  1. #1· Wizards of the Coast

    “Exiled this way” refers to the exile instruction that’s part of Scrap Mastery’s effect. If the sacrificed artifacts are instead exiled because of a replacement effect, those cards won’t be put onto the battlefield.
