Extruder — ruling 1

Extruder can be the target of its own activated ability, and you can sacrifice Extruder to pay for that activation. This won't accomplish much, but it does allow you to sacrifice Extruder if you want to.

Extruder — ruling 2

Paying for echo is always optional. When the echo triggered ability resolves, if you can't pay the echo cost or choose not to, you sacrifice that permanent.

Extruder — ruling 3

Your permanent's echo ability will trigger at the beginning of your upkeep if it entered the battlefield since the beginning of your last upkeep, or if you gained control of it since the beginning of your last upkeep.

Extruder : règles, fonctionnement et interactions (MTG)

Extruder 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

Echo (At the beginning of your upkeep, if this came under your control since the beginning of your last upkeep, sacrifice it unless you pay its echo cost.) Sacrifice an artifact: Put a +1/+1 counter on target creature.

Complete guide

Extruder is a versatile Juggernaut from Urza's Destiny that serves as a powerful sacrifice outlet for artifact-heavy decks. While it demands a mana investment through its echo cost, its ability to convert spare artifacts into permanent power makes it a dangerous presence on the battlefield.

Understanding the Echo Cost

Extruder features the Echo keyword, which represents a one-time payment required during your upkeep. If Extruder entered the battlefield or you gained control of it since the start of your last upkeep, a trigger goes on the stack. You must then choose to either pay its mana cost of four generic mana or sacrifice it. If you cannot pay or choose not to, the creature is put into the graveyard.

Turning Scrap into Strength

The core of Extruder is its activated ability: 'Sacrifice an artifact: Put a +1/+1 counter on target creature.' This is a fast, mana-free way to grow your board. Since Extruder is an artifact itself, it can sacrifice itself to its own ability. While the +1/+1 counter won't stay on Extruder if it is sacrificed this way, you can still use this to target another creature you control before Extruder leaves the battlefield.

Strategic Deployment

You should play Extruder when you have non-creature artifacts that have already served their purpose or creatures with powerful 'dies' triggers. It is best used as a finisher; by sacrificing your entire board of artifacts at once, you can pump a single unblocked creature to lethal proportions. Just remember that the Echo cost will trigger on your next turn, so plan your mana accordingly.

Interaction examples

The Value Engine

Solemn Simulacrum

With both on the field, you can sacrifice Solemn Simulacrum to Extruder's ability. This puts a +1/+1 counter on a target creature and triggers Solemn Simulacrum's ability, allowing you to draw a card. This effectively turns a utility creature into both a buff and card draw.

Double the Echo Trouble

Roaming Throne

If Roaming Throne enters and you choose 'Juggernaut', it will see Extruder's Echo ability trigger during your upkeep. Because Echo is a triggered ability, Roaming Throne causes it to trigger an additional time. You would have to pay the Echo cost twice or sacrifice Extruder to the first resolving trigger.

Self-Sacrifice Play

If an opponent tries to exile Extruder with a spell, you can respond by activating its ability, sacrificing Extruder itself as the cost. You can target another creature you control to receive a +1/+1 counter, ensuring Extruder goes to the graveyard instead of exile while still providing a benefit.
