Saheeli's first ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

Saheeli, Sublime Artificer — ruling 2

Saheeli, Sublime Artificer : règles, fonctionnement et interactions (MTG)

Saheeli, Sublime Artificer 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 a noncreature spell, create a 1/1 colorless Servo artifact creature token. −2: Target artifact you control becomes a copy of another target artifact or creature you control until end of turn, except it's an artifact in addition to its other types.

Complete guide

Saheeli, Sublime Artificer is a versatile hybrid-mana planeswalker that excels in spell-heavy decks. She provides both a constant stream of blockers and the ability to transform your utility artifacts into powerful threats or engine pieces.

Manufacturing Servos

Saheeli's passive ability triggers whenever you cast a noncreature spell. This trigger goes on the stack on top of the spell you just cast, meaning you will receive a 1/1 colorless Servo artifact creature token before your spell actually resolves. Even if your opponent counters your spell, you still get to keep the Servo.

The Art of Transmutation

Her -2 loyalty ability allows one target artifact you control to become a copy of another target artifact or creature you control until end of turn. The target artifact keeps its identity as an artifact in addition to its new types. Note that this effect only copies the 'copiable values' of the target, such as name, mana cost, and printed abilities. It does not copy temporary stat buffs, counters, or effects that turned a noncreature permanent into a creature.

Strategic Timing

Because Saheeli's copy ability lasts until the end of the turn, it is often best used during your main phase to transform a Servo into a copy of a powerful creature you already have. However, remember that if the artifact entered the battlefield this turn, it will have 'summoning sickness' once it becomes a creature, meaning it cannot attack or tap unless it has haste.

Common Pitfalls

A common mistake is forgetting that the copy effect wears off during the cleanup step. If you copy an Equipment and attach it to a creature, it will fall off once the artifact reverts to its original form unless that original form was also an Equipment. Additionally, remember that copying a legendary permanent will trigger the 'legend rule,' requiring you to put one of them into the graveyard.

Interaction examples

Generating Tokens with Narset

Narset, Parter of Veils

When you cast Narset, Parter of Veils while Saheeli is on the battlefield, Saheeli's passive ability triggers because Narset is a noncreature spell. You will create a 1/1 Servo token first, and then Narset will resolve and enter the battlefield.

Doubling Down on Jace

Jace, Wielder of Mysteries Servo

Servo

If you have Jace, Wielder of Mysteries and a Servo token on the field, you can use Saheeli's -2 ability to turn the Servo into a copy of Jace. Because Jace is Legendary, you must choose one to keep and put the other into the graveyard. If you keep the copy, it will be an Artifact Legendary Planeswalker — Jace with the same starting loyalty as the printed card, not the current loyalty of the original.

Protective Blocking

Servo

During your opponent's turn, if they cast a spell that you counter with a noncreature spell, Saheeli triggers. You create a Servo token immediately, which can then be used as a surprise blocker for an incoming attacker before your counterspell even finishes resolving.
