Birgi, God of Storytelling // Harnfel, Horn of Bounty

Seething Song

Reiterate

How it works

1. Cast Seething Song by paying 2.
2. Birgi triggers, adding .
3. Holding priority, cast Reiterate with buyback by paying 4, targeting Seething Song.
4. Birgi triggers, adding .
5. Resolve Reiterate, copying Seething Song and returning Reiterate to your hand.
6. Resolve the copy of Seething Song, adding .
7. Repeat from step 3.

This explosive loop revolves around leveraging Birgi, God of Storytelling's passive mana-generating trigger to fund an ever-repeating cycle of instant-speed recursion. By casting Seething Song, you generate an initial burst of mana and net red mana from Birgi, God of Storytelling's front face whenever any spell is cast. You then funnel that mana into Reiterate with its buyback cost paid, targeting the original Seething Song so the copy safely resolves and feeds you a surplus of red mana. Because Reiterate bounces right back to your hand upon resolution, you can endlessly repeat this exact sequence to generate infinite storm count and magecraft triggers.
