Galvanic Iteration + Skull Storm

Overview

If you cast Skull Storm while Galvanic Iteration’s delayed ability is watching for your next instant or sorcery, both triggers (the Iteration delayed trigger and Skull Storm’s own “When you cast this spell…” trigger) will trigger when you cast Skull Storm . When those triggers resolve they put copies of Skull Storm onto the stack; those copies are not cast and therefore do not cause Skull Storm’s "when you cast" trigger to trigger again ; see Ruling [2018-07-13]. You choose the order your simultaneous triggers go on the stack and that ordering determines the order the copies are produced on resolution .

Step 1

You cast Galvanic Iteration and it resolves; it creates a delayed trigger that reads 'When you next cast an instant or sorcery spell this turn, copy that spell.' That delayed trigger will trigger the next time you cast an instant or sorcery this turn .

Step 2

You then cast Skull Storm. When Skull Storm becomes cast, two things happen at that moment: Skull Storm’s own triggered ability ('When you cast this spell, copy it for each time you've cast your commander from the command zone this game') triggers, and Galvanic Iteration’s delayed trigger also triggers because you cast an instant or sorcery .

Step 3

Both triggered abilities go on the stack at the same time. If they are triggers you control, you put them on the stack in the order you choose; that ordering determines which trigger will resolve first .

Step 4

When the Skull Storm triggered ability resolves it creates the number of copies equal to the number of times you’ve cast your commander from the command zone and puts those copies onto the stack. Those copies are created on the stack and are not cast, so they do not themselves cause any 'when you cast' triggers to trigger ; Ruling [2018-07-13].

Step 5

When the Galvanic Iteration delayed trigger resolves it copies 'that spell'—the Skull Storm you cast (the original spell that caused the trigger)—and puts that copy onto the stack. That copy is also not cast .

Step 6

Each copy on the stack (the copies from Skull Storm’s triggered ability and the copy from Galvanic Iteration) will resolve as a spell on the stack and carry out Skull Storm’s effect (each opponent sacrifices a creature or loses half their life, rounded up). None of those copies will cause additional 'when you cast this spell' triggers because they were not cast ; Ruling [2018-07-13].

Resolution

Galvanic Iteration copies the Skull Storm you cast (its delayed trigger will put a copy of the original Skull Storm onto the stack), and Skull Storm’s own triggered ability will put its copies onto the stack for the number of times you cast your commander from the command zone. All copies are created on the stack and are not cast, so copies do not themselves cause Skull Storm’s trigger to trigger again ; Ruling [2018-07-13].
