Carte Magic Krark-Clan Ironworks

Krark-Clan Ironworks 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

Sacrifice an artifact: Add {C}{C}.

Complete guide

Krark-Clan Ironworks is a cornerstone of artifact-based combo decks, providing a massive influx of mana by breaking down your own machines. As a powerful sacrifice outlet, it turns every spare bauble into fuel for your next big play. Understanding the timing of this mana ability is key to mastering your resource management.

Converting Metal to Mana

Krark-Clan Ironworks features a single activated ability that allows you to sacrifice an artifact to add two colorless mana to your mana pool. Because this ability generates mana and does not require a target, it is a mana ability. This means it does not use the stack and cannot be responded to by your opponents; the mana is added instantly as soon as you pay the cost by sacrificing an artifact.

Step-by-Step Resolution

To use Krark-Clan Ironworks, you announce you are activating the ability. You choose an artifact you control and move it to the graveyard as the payment. Immediately after the sacrifice, two colorless mana ({C}{C}) are added to your mana pool. This can be done any time you have priority, or even while you are in the middle of casting another spell or activating another ability that requires a mana payment.

Timing and Strategy

A common mistake is forgetting that you can only sacrifice artifacts you already have on the battlefield. You cannot sacrifice a card while it is still a spell on the stack. Additionally, while the mana ability itself doesn't use the stack, any 'dies' triggers resulting from the sacrifice will use the stack and can be responded to after you finish the current action.

Interaction examples

Recycling the Golem

You have Solemn Simulacrum on the battlefield. You activate Krark-Clan Ironworks by sacrificing the Golem. You immediately receive {C}{C}. Because Solemn Simulacrum was put into the graveyard, its triggered ability goes on the stack, allowing you to draw a card after the mana has already been produced.

Double Value Extraction

You control Commander's Sphere and Krark-Clan Ironworks. You have a choice: you can sacrifice Commander's Sphere to its own ability to draw a card, or sacrifice it to Krark-Clan Ironworks for {C}{C}. You cannot do both, as you can only pay one sacrifice cost for one effect. If you choose the Ironworks, you get the mana but do not draw the card from the Sphere's own sacrifice ability.
