Spellbinding Soprano + Sprout Swarm + Docent of Perfection // Final Iteration

Spellbinding Soprano

Sprout Swarm

Docent of Perfection // Final Iteration

How it works

1. Activate Spellbinding Soprano's encore ability by paying 3 and exiling it from your graveyard, creating a token copy of it with haste for each opponent you have.
2. Declare each Spellbinding Soprano token as an attacker.
3. Each Spellbinding Soprano token triggers, causing instant and sorcery spells you cast this turn to cost 1 less to cast for each Spellbinding Soprano token.
4. Cast Sprout Swarm with buyback by tapping a green creature and any other creature you control.
5. Docent of Perfection triggers, creating a 1/1 Human Wizard creature token.
6. Resolve Sprout Swarm, creating a 1/1 Saproling creature token and returning Sprout Swarm to your hand.
7. Repeat from step 4.

This ingenious loop harnesses the cost-reducing power of Spellbinding Soprano's attack trigger, which discounts your instant and sorcery spells for each token copy generated through its encore ability. By fueling Sprout Swarm with convoke, you can pay for the spell using the very creatures it helps create, leveraging the buyback cost to endlessly loop the spell back into your hand. Meanwhile, Docent of Perfection watches over your spellcasting to churn out Human Wizard tokens, eventually transforming into Final Iteration to pump your entire flying army while continuing to trigger off every iteration of Sprout Swarm.
