Druid's Call + Brash Taunter + Pandemonium

Druid's Call

Brash Taunter

Pandemonium

How it works

1. Deal damage to Brash Taunter.
2. Brash Taunter and Druid's Call triggers.
3. Resolve the Brash Taunter trigger, dealing that much damage to target opponent.
4. Resolve the Druid's Call trigger, creating that many 1/1 Squirrel creature tokens.
5. Each Squirrel enters the battlefield, triggering Pandemonium that many times.
6. Resolve all but one Pandemonium triggers, causing the Squirrels to each deal one damage to any target.
7. Resolve the final Pandemonium trigger, causing a Squirrel to deal one damage to Brash Taunter.
8. Repeat from step 2.
