Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Pir, Imaginative Rascal + Deathbringer Thoctar

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Pir, Imaginative Rascal

Deathbringer Thoctar

How it works

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

This clever setup relies on Agatha's Soul Cauldron to grant activated abilities to your creatures, with Deathbringer Thoctar's lethal sniping ability exiled inside it and shared across your board via +1/+1 counters. Pir, Imaginative Rascal acts as the ultimate multiplier, ensuring that every time Anti-Venom, Horrifying Healer prevents self-inflicted damage or receives a counter, Pir adds an extra one to fuel the loop infinitely. Because Anti-Venom, Horrifying Healer enters the battlefield by returning a creature from your graveyard, you can easily assemble this engine and direct an endless stream of damage to any target.
