Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Triskelion + Caradora, Heart of Alacria

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Triskelion

Caradora, Heart of Alacria

How it works

1. Activate Anti-Venom using Triskelion'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 Caradora.
2. Activate Anti-Venom using Triskelion's ability by removing a +1/+1 counter from it, dealing 1 damage to any target.
3. Repeat.

This intricate loop turns self-inflicted damage into an endless engine of destruction by turning Anti-Venom, Horrifying Healer into a lethal turret. Thanks to Agatha's Soul Cauldron, Anti-Venom gains the activated ability of Triskelion while it holds +1/+1 counters, allowing it to shoot targets or itself. Meanwhile, Caradora, Heart of Alacria acts as the ultimate amplifier, ensuring that every time Anti-Venom prevents its own self-inflicted damage and places counters, it nets a surplus.
