Birgi, God of Storytelling // Harnfel, Horn of Bounty + Reiterate + Seething Song

Overview

When you cast Seething Song and you cast Reiterate targeting that Seething Song, Birgi will trigger twice (once for casting Seething Song and once for casting Reiterate); each Birgi trigger, when it resolves, adds {R}

that won’t be removed as steps and phases end. Reiterate’s copy of Seething Song is put onto the stack but is not cast, so it does not cause Birgi to trigger . Buyback on Reiterate must be paid as Reiterate is cast and cannot be paid using mana produced later by Birgi’s triggers, because buyback is an additional cost paid while casting the spell and mana abilities must be activated before costs are paid .

Step 1

You cast Seething Song: follow the casting steps and pay its cost; as part of casting it, after the casting is complete its 'Whenever you cast a spell' trigger from Birgi is created and put on the stack .

Step 2

With Birgi’s trigger on the stack, you may respond by casting Reiterate targeting the Seething Song already on the stack; you must declare whether you pay Reiterate’s buyback as you cast it (buyback is an additional cost that must be announced and paid as you cast) .

Step 3

Casting Reiterate creates a second Birgi trigger (because you cast a second spell); that trigger is put on the stack after the Reiterate spell itself is placed on the stack .

Step 4

Players pass priority and the topmost objects resolve in LIFO order: first the Birgi trigger from Reiterate resolves, adding {R}

that 'you don't lose as steps and phases end' (that mana is added to your mana pool and the protection applies to that mana). This is a triggered ability resolving, not a spell being cast .

Step 5

Next Reiterate resolves: it copies the targeted instant or sorcery spell (Seething Song) and puts that copy onto the stack. Reiterate then returns to your hand if you paid buyback as you cast it .

Step 6

The Seething Song copy resolves (it was put onto the stack by Reiterate but it was not cast), and adds {R}

to your mana pool when it resolves . Because the copy was not cast, Birgi does not trigger for that copy .

Step 7

Then the Birgi trigger that was created when you originally cast Seething Song resolves, adding another {R}

that persists until end of turn.

Step 8

Finally the original Seething Song resolves and adds {R}

to your mana pool. Net result (with both Birgi triggers resolving and both the original and copy resolving): two persistent {R}

from Birgi plus 5 {R}

from the copy and 5 {R}

from the original for a total of 12 {R}

in the pool (the two Birgi {R}

are protected from being removed as steps and phases end).

Resolution

If you cast Seething Song, then cast Reiterate targeting that Seething Song, the stack (top → bottom) will typically be: Birgi trigger from Reiterate, Reiterate, Birgi trigger from Seething Song, Seething Song. When everything resolves you will get two Birgi {R}

(each of which persists until end of turn as Birgi’s ability states) plus the mana from the Seething Song copy (5 {R}

) and the original Seething Song (5 {R}

). The copy created by Reiterate is not cast and therefore does not trigger Birgi ; buyback must be paid when casting Reiterate and cannot use mana produced by Birgi triggers that resolve after casting .
