Agatha's Soul Cauldron + Inquisitive Puppet + Master Biomancer

Agatha's Soul Cauldron

Inquisitive Puppet

Master Biomancer

How it works

1. Activate another creature you control that has a +1/+1 counter on it by exiling it, creating a 1/1 Human creature token that enters the battlefield with at least two +1/+1 counters on it due to Master Biomancer.
2. Repeat using the Human token instead.

This clever loop transforms graveyard exiling into an engine for infinite creature entries and exits by leveraging Agatha's Soul Cauldron to grant activated abilities across your board. While the Cauldron allows you to exile creatures and place +1/+1 counters on your side, Inquisitive Puppet provides the crucial sacrifice-and-exile ability to kick off the chain. Master Biomancer ties the whole operation together with its static ability, ensuring every newly created 1/1 Human token enters with enough +1/+1 counters to immediately use the Cauldron's ability again.
