Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Walking Ballista + Doc Samson, Super Psychiatrist

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Walking Ballista

Doc Samson, Super Psychiatrist

How it works

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

This brilliant loop turns Walking Ballista into a self-sustaining engine by utilizing Agatha's Soul Cauldron to grant its activated ping ability to Anti-Venom, Horrifying Healer, who now carries the Ballista's name and identity in the cauldron's eyes. Doc Samson, Super Psychiatrist supercharges the entire cycle by replacing any incoming +1/+1 counter with an extra one, ensuring that when Anti-Venom prevents its own simulated damage or receives counters, it grows larger rather than just breaking even. By constantly removing a counter to deal 1 damage to any target and cycling it back with surplus counters, you rapidly generate infinite damage and infinite +1/+1 counters.
