Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Triskelion + Gratuitous Violence

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Triskelion

Gratuitous Violence

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 Gratuitous Violence.
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 clever loop centers around Agatha's Soul Cauldron, which grants your creatures the activated abilities of any creature cards exiled within it while also allowing you to spend mana of any color. By exiling Triskelion into the Cauldron, your creatures gain its lethal ability to ping any target by removing a +1/+1 counter. Anti-Venom, Horrifying Healer acts as the vessel for this granted ability, using its unique replacement effect to convert the self-inflicted damage into a surplus of +1/+1 counters—a growth spurt that is dramatically amplified by Gratuitous Violence doubling the damage output. The result is an explosive engine capable of generating infinite damage and infinite counters to sweep the board and close out the game.
