Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Dictate of the Twin Gods + Walking Ballista

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Dictate of the Twin Gods

Walking Ballista

How it works

1. Activate Anti-Venom using Walking Ballista's ability by removing a +1/+1 counter from it, targeting itself and putting two +1/+1 counters on it due to its replacement effect and Dictate of the Twin Gods.
2. Activate Anti-Venom using Walking Ballista's ability by removing a +1/+1 counter from it, dealing 1 damage to any target.
3. Repeat.

This ingenious loop begins when Agatha's Soul Cauldron banishes Walking Ballista from the graveyard, granting Anti-Venom, Horrifying Healer the ability to remove a +1/+1 counter to deal 1 damage. With Dictate of the Twin Gods doubling the resulting damage onto Anti-Venom itself, the symbiote's own replacement effect steps in to convert that prevented damage into a surplus of +1/+1 counters. Because Agatha's Soul Cauldron also allows you to spend mana of any color, you can continuously tap into these accumulated counters to fuel Walking Ballista's devastating ping ability over and over again.
