Anti-Venom, Horrifying Healer + Agatha's Soul Cauldron + Triskelion + Lae'zel, Vlaakith's Champion

Anti-Venom, Horrifying Healer

Agatha's Soul Cauldron

Triskelion

Lae'zel, Vlaakith's Champion

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 Lae'zel.
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 lethal loop turns self-inflicted damage into exponential growth by weaving together a clever set of activated abilities and replacement effects. With Agatha's Soul Cauldron exiling Triskelion to grant its ping ability to your creatures, Lae'zel, Vlaakith's Champion steps in as the ultimate multiplier, ensuring that every time Anti-Venom, Horrifying Healer prevents self-inflicted damage and places counters, you actually gain a net surplus. By constantly cycling Triskelion's damage-dealing ability through Anti-Venom's damage-prevention trigger, you rapidly churn out boundless +1/+1 counters and infinite damage to close out the game.
