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

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Deathbringer Thoctar

Caradora, Heart of Alacria

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 Caradora.
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 loop is ignited by Agatha's Soul Cauldron, which allows your creatures to inherit the activated abilities of any creature cards exiled within it. By exiling Deathbringer Thoctar to the Cauldron, its deadly counter-removing strike is granted to Anti-Venom, Horrifying Healer. As Anti-Venom self-damages to fuel this ability, its prevention replacement effect converts that prevented damage into +1/+1 counters, a yield further supercharged by Caradora, Heart of Alacria's replacement effect which tacks an extra counter onto the pile. This surplus of counters feeds right back into the engine, letting you endlessly repeat the process to blast away any target with infinite damage.
