Lae'zel, Vlaakith's Champion + Druid's Call + Cathars' Crusade + Triskelion

Lae'zel, Vlaakith's Champion

Druid's Call

Cathars' Crusade

Triskelion

How it works

1. Activate Triskelion by removing a +1/+1 counter from it, dealing 1 damage to itself.
2. Druid's Call triggers, creating a 1/1 Squirrel creature token.
3. When the Squirrel enters the battlefield, Cathars' Crusade triggers, putting two +1/+1 counters on each creature you control.
4. Repeat.
5. During the next player's turn, you may remove all of the +1/+1 counters from Triskelion to deal infinite damage to any target(s).

This fascinating loop turns Triskelion's self-inflicted damage into an engine of exponential growth, starting when you enchant it with Druid's Call to trigger a swarm of Squirrel tokens whenever it takes damage. Each time a token enters, Cathars' Crusade pumps up your board, while Lae'zel, Vlaakith's Champion ensures those growth-tracking +1/+1 counters pile on even faster by adding an extra counter to every batch placed. By continually shooting Triskelion for one damage to spawn tokens that buff it back up, you stockpile limitless counters to eventually unleash infinite damage and an infinite army.
