Stitcher's Supplier 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

When this creature enters or dies, mill three cards. (Put the top three cards of your library into your graveyard.)

Complete guide

Stitcher's Supplier is a staple in graveyard-based strategies, offering incredible value for just a single black mana. This efficient Zombie ensures your graveyard is well-stocked both when it arrives on the battlefield and when it departs. Understanding the timing of its triggers is key to maximizing its potential in your next match.

What it Does

Stitcher's Supplier has a triggered ability that occurs at two distinct moments: when it enters the battlefield and when it dies. Each time this trigger resolves, you mill three cards. Milling means taking the top cards of your library and putting them directly into your graveyard. Since it triggers on both entry and death, a single copy can reliably put six cards into your graveyard over its life cycle.

How it Resolves Step by Step

When Stitcher's Supplier enters the battlefield, its ability is put onto the stack. Once players pass priority, the ability resolves and you mill three cards. If the creature later dies (is moved from the battlefield to the graveyard), the ability triggers again. It does not matter how the creature dies—whether through combat, being sacrificed, or an opponent's destruction spell—the second mill trigger will always occur as long as it successfully moves to the graveyard.

Common Mistakes

A common point of confusion is what happens if Stitcher's Supplier is exiled instead of destroyed. The 'dies' trigger only functions if the card is moved specifically from the battlefield to the graveyard. If an effect exiles the card directly from the battlefield, the second mill trigger will not happen. Additionally, remember that milling is not optional; you must mill exactly three cards if they are available in your library.

When to Play It

This card is best utilized in decks that treat the graveyard as a second hand. It is a perfect turn-one play to set up future plays that require cards in the graveyard, such as Reanimate targets or Delve costs. It also serves as excellent 'chump block' fodder, as your opponent may be hesitant to kill it and grant you three more cards in your graveyard.

Interaction examples

Stacking Death Triggers

Blood Artist

If you have both creatures on the battlefield and Stitcher's Supplier dies, two triggers go on the stack: Stitcher's Supplier's mill ability and Blood Artist's life drain ability. As the active player, you choose the order in which they are placed on the stack. You can choose to mill three cards first, potentially putting more creatures in the graveyard, and then resolve the life gain/loss effect.

Maximizing Early Game Setup

Ornithopter of Paradise

On turn one, you cast Stitcher's Supplier and mill three cards. On turn two, you cast Ornithopter of Paradise to fix your mana. If you later use a sacrifice effect to get rid of the Supplier, you mill another three cards. This sequence allows you to build a board presence with the Thopter while the Supplier ensures your graveyard is deep enough for mid-game synergies.
