Prismari Pianist : règles, fonctionnement et interactions (MTG)

Prismari Pianist 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

Whenever you cast an instant or sorcery spell, create a 1/1 blue and red Elemental creature token. If that spell's mana value is 5 or greater, create three of those tokens instead.

Complete guide

Prismari Pianist turns every instant or sorcery spell you cast into a small Elemental ensemble. Spells with mana value 5 or greater produce three tokens instead of one—and the tokens normally arrive before the spell resolves.

What It Does

Prismari Pianist is a Djinn Bard that costs {1}{R}{R}. Whenever you cast an instant or sorcery spell while you control it on the battlefield, its ability triggers. That ability creates one 1/1 blue and red Elemental creature token, or three of those tokens instead if the spell's mana value is at least 5. The larger result is three tokens total, not one plus three. Casting a creature spell doesn't trigger this ability, and simply copying a spell on the stack doesn't count as casting it.

How It Resolves, Step by Step

First, you cast an instant or sorcery spell. Prismari Pianist's ability triggers and goes on the stack above that spell before a player next receives priority. Players may respond. When the triggered ability resolves, it creates the appropriate number of tokens; the original spell remains on the stack to resolve later if nothing else intervenes. Mana value comes from the spell's mana cost, not the amount of mana you actually paid. Alternative costs, additional costs, cost increases, and cost reductions don't change it. For a spell with {X} in its mana cost, use the chosen value of X while that spell is on the stack. Example 1 — Roaming Throne doubles the performance: You control Prismari Pianist and Roaming Throne, with Djinn chosen for Roaming Throne. You cast an instant or sorcery spell with mana value 5 or greater. Prismari Pianist's ability triggers twice because it is another creature you control of the chosen type. Each trigger resolves separately and creates three Elemental tokens, for six total, before the spell resolves. Choosing Bard instead of Djinn also works; choosing Elemental doesn't make Roaming Throne double Prismari Pianist's ability.

Common Mistakes and Important Boundaries

Countering the instant or sorcery spell doesn't counter Prismari Pianist's triggered ability. Once triggered, that ability exists independently of both the spell and Prismari Pianist. It can still resolve if the spell is countered or Prismari Pianist leaves the battlefield. If the spell has left the stack, the ability uses its last known information to determine its mana value. Example 2 — Solemn Simulacrum isn't a qualifying spell: You control Prismari Pianist and cast Solemn Simulacrum. Because it is an artifact creature spell, Prismari Pianist doesn't trigger. When Solemn Simulacrum resolves and enters the battlefield, its own ability triggers, allowing you to search for a basic land card, put it onto the battlefield tapped, then shuffle. That triggered ability isn't a spell you cast, so it doesn't trigger Prismari Pianist either.

When to Play It

Get Prismari Pianist onto the battlefield before casting the instants and sorceries you want it to reward. Its tokens can build your battlefield while your spells do their own work, but they have no haste from this ability: tokens created during your turn normally can't attack that turn. Example 3 — Setting up blockers with Roaming Throne: You control Prismari Pianist and Roaming Throne with Bard chosen. During an opponent's turn, before attackers are declared, you cast an instant spell with mana value less than 5. Prismari Pianist triggers twice, and each resolving trigger creates one Elemental token. Once those tokens are on the battlefield, they can block that turn if they remain available when blockers are declared. Newly created creatures aren't prevented from blocking by the rule that restricts attacking and using their own tap-symbol or untap-symbol abilities.
