Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Deathbringer Thoctar + Sawhorn Nemesis

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Deathbringer Thoctar

Sawhorn Nemesis

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 Sawhorn Nemesis.
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 ingenious loop transforms your creatures into an unyielding engine of destruction by leveraging Agatha's Soul Cauldron to grant Deathbringer Thoctar's activated ability to Anti-Venom, Horrifying Healer. Once Anti-Venom absorbs that ability, it can target itself with its own newly acquired ping, while Sawhorn Nemesis doubles that damage into a surge of extra +1/+1 counters via Anti-Venom's replacement effect. You then use Deathbringer Thoctar's ability to ping any target for the win, cycling the counters back and forth to fuel infinite damage and infinite +1/+1 counters.
