Druid's Call + Cathars' Crusade + Triskelion + Hardened Scales

Druid's Call

Cathars' Crusade

Triskelion

Hardened Scales

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 clever loop turns Triskelion into a self-contained damage engine by having it shoot itself to fuel Druid's Call, which floods the board with Squirrel tokens whenever damage is dealt to the enchanted creature. Each time a token enters, Cathars' Crusade triggers to pump your entire board, a process vastly amplified by Hardened Scales adding an extra counter to every creature whenever they receive them. The beauty of this synergy is that the counters placed on Triskelion by Cathars' Crusade and Hardened Scales completely outpace the ones you remove to deal damage, letting you infinitely grow your team, generate endless tokens, and eventually redirect that lethal payload anywhere you choose.
