Spellbinding Soprano + Sprout Swarm + Chatterfang, Squirrel General

Spellbinding Soprano

Sprout Swarm

Chatterfang, Squirrel General

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

This clever engine takes advantage of cost reduction and token doubling to cast spells infinitely. By utilizing Spellbinding Soprano's encore ability, your attacking token copies reduce the cost of instant and sorcery spells you cast this turn by at least two generic mana. This discount makes Sprout Swarm exceptionally cheap to cast, allowing you to pay its buyback cost repeatedly. Meanwhile, Chatterfang, Squirrel General watches every token creation event and doubles your yield by generating an extra Squirrel alongside every Saproling, easily fueling convoke and generating an endless army.
