Leech Bonder + Song of Freyalise + Corpsejack Menace

Leech Bonder

Song of Freyalise

Corpsejack Menace

How it works

1. Activate Leech Bonder by tapping it, adding .
2. Activate Leech Bonder by paying and untapping it, removing a +1/+1 counter from target creature and putting two +1/+1 counters on a different creature due to Corpsejack Menace.
3. Repeat.

This clever loop transforms Leech Bonder—a creature that normally shuffles -1/-1 counters around—into an infinite growth engine by exploiting the replacement effect of Corpsejack Menace. With Song of Freyalise providing the initial colored mana source through its first two chapters to pay Leech Bonder's activation cost, every iteration of moving counters results in a net gain. Because Corpsejack Menace doubles any +1/+1 counters placed on your creatures, the counter you move off one creature turns into two on the next, allowing you to cycle the counters back and forth to grow your board infinitely large.
