Carte Magic Stormsplitter

Stormsplitter 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

Haste Whenever you cast an instant or sorcery spell, create a token that's a copy of this creature. Exile that token at the beginning of the next end step.

Complete guide

Stormsplitter is a volatile Otter Wizard that quickly multiplies whenever you harness the power of magic. With its Haste ability and a penchant for replication, it can turn a single turn of spellcasting into an overwhelming tidal wave of creatures. Understanding how these copies interact with each other is the key to mastering this card's explosive potential.

Exponential Growth

The core of Stormsplitter is its triggered ability: whenever you cast an instant or sorcery spell, you create a token copy of the creature. Crucially, because these tokens are exact copies, they also possess the same triggered ability. This means that if you have one Stormsplitter and cast a spell, you get a second one. If you then cast another spell, both the original and the token trigger, giving you two more tokens for a total of four.

The Anatomy of a Copy

When Stormsplitter creates a token, it copies the 'copiable values' of the creature. This includes the name, mana cost, types, and all printed text. It does not copy temporary effects like +1/+1 counters, Auras, or power modifications from other spells. If Stormsplitter leaves the battlefield before the ability resolves, the game uses its last known information to determine what the token looks like. If Stormsplitter is currently copying something else, the token will be a copy of that new form.

Cleanup and Timing

Every token created by Stormsplitter has a built-in expiration date: it must be exiled at the beginning of the next end step. Because this happens at the start of the end step, any spells you cast during an opponent's turn will create tokens that last until the end of that specific turn. If you cast a spell during your own end step, however, the next end step isn't until the following player's turn, allowing those tokens to stick around for defense.

Interaction examples

The Throne's Influence

If you have Roaming Throne on the battlefield with 'Otter' chosen as the creature type, casting an instant or sorcery will cause Stormsplitter's ability to trigger twice. You will create two tokens immediately. If you then cast a second spell, the original Stormsplitter and the two new tokens will each trigger twice, resulting in six additional tokens being created in a single step.

Basic Mechanics

If you cast Stormsplitter and then cast an instant spell like Opt, the Stormsplitter triggers and creates a token. Both the original and the token have Haste, allowing you to attack for 2 damage immediately. At the beginning of your end step, the token is exiled, but the original Stormsplitter remains for your next turn.

Non-Synergy Check

Stormsplitter only triggers on the casting of 'Instant' or 'Sorcery' spells. If you cast Solemn Simulacrum, which is a creature spell, Stormsplitter will not trigger and no tokens will be created. The Otter Wizard requires pure magical energy, not artifacts, to replicate itself.

How it works : Stormsplitter

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    The token copy will have Stormsplitter’s abilities and will be able to create copies of itself.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    The token doesn’t copy whether Stormsplitter is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    If Stormsplitter splits… er, leaves the battlefield before its triggered ability resolves, the token will still enter as a copy of Stormsplitter, using Stormsplitter’s copiable values from when it was last on the battlefield.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    In the unusual case where Stormsplitter becomes a copy of something else while its triggered ability is on the stack but before it resolves, the token will enter as a copy of whatever Stormsplitter is copying.

    No other card is named in this ruling.
