Elemental Expressionist — ruling 1

Elemental Expressionist has received an update to its Oracle text. Specifically, the second ability granted to the target creature doesn't care that the creature's controller is the one exiling it. If the creature is put into exile for any reason, that ability will trigger.

Elemental Expressionist — ruling 2

If you target a creature token with Elemental Expressionist's ability, and that token would leave the battlefield, it is still exiled (very briefly) before it ceases to exist, and you will still create an Elemental token.

Elemental Expressionist — ruling 3

If the magecraft ability triggers and resolves more than once with the same creature as the target, that creature will have multiple instances of each of the two triggered abilities the magecraft ability grants it. Each instance of the second ability will trigger separately, and you'll create an Elemental token for each of them. (Multiple instances of the first granted ability are redundant.)

Elemental Expressionist — ruling 4

Each magecraft ability has a different effect, although they all have the same trigger condition, whenever you cast or copy an instant or sorcery spell.

Elemental Expressionist — ruling 5

For example, if you control Archmage Emeritus and cast an instant or sorcery spell, Archmage Emeritus's magecraft ability will trigger and you will draw a card.

Elemental Expressionist — ruling 6

If an effect creates a copy of an instant or sorcery spell, this will also cause the magecraft ability to trigger.

Elemental Expressionist — ruling 7

If an effect creates multiple copies of an instant or sorcery spell, magecraft abilities trigger once for each copy created by the effect.

Elemental Expressionist — ruling 8

Some effects instruct you to copy an instant or sorcery card in a zone other than the stack. These copies do not cause magecraft abilities to trigger. However, most effects that do this also allow you to cast the copy, and casting the copy will cause magecraft abilities to trigger.

Elemental Expressionist : règles, fonctionnement et interactions (MTG)

Elemental Expressionist 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

Magecraft — Whenever you cast or copy an instant or sorcery spell, choose target creature you control. Until end of turn, it gains "If this creature would leave the battlefield, exile it instead of putting it anywhere else" and "When this creature is put into exile, create a 4/4 blue and red Elemental creature token." (Each instance of that ability triggers separately.)
