Clever Conjurer + Porcuparrot + Illusionist's Bracers

Clever Conjurer

Porcuparrot

Illusionist's Bracers

How it works

1. Activate the Porcuparrot pile, tapping it to untap itself.
2. Illusionist's Bracers triggers, copying the Porcuparrot ability.
3. Resolve the copy of the ability, untapping the Porcuparrot stack.
4. Holding priority, activate the Porcuparrot pile by tapping it to deal damage equal to the amount of times it has mutated to any target.
5. Resolve the original Porcuparrot untap ability, untaping it.
6. Repeat.
