Spellbinding Soprano + Sprout Swarm + Queen Allenal of Ruadach

Spellbinding Soprano

Sprout Swarm

Queen Allenal of Ruadach

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, creating a 1/1 Soldier and a 1/1 Saproling creature token and returning Sprout Swarm to your hand.
5. Repeat step 4.

This brilliant loop turns a humble common into an infinite token-generating machine by heavily discounting its cost. When you activate Spellbinding Soprano's encore ability, your attacking token copies trigger to massively reduce the cost of your instant and sorcery spells for the turn. This discount is precisely what makes Sprout Swarm so explosive, as its buyback cost becomes entirely free to pay through convoke. Meanwhile, Queen Allenal of Ruadach supercharges the board by doubling up every single token creation with an extra Soldier, fueling your convoke army and pushing her own power to astronomical heights.
