Cause an artifact to enter the battlefield under your control.
Weftstalker Ardent triggers, dealing 1 damage to each opponent.
Malcolm triggers, as Weftstalker Ardent is a Pirate due to Captain's Hook, creating a Treasure token for each opponent dealt damage this way.
When the Treasure(s) enter, Weftstalker Ardent triggers that many times.
Resolve the first Weftstalker Ardent trigger, dealing 1 damage to each opponent.
Repeat from step 3.
This delightful loop transforms the humble act of a permanent entering the battlefield into an unstoppable cascade of fiery destruction and glittering wealth. It all hinges on Captain's Hook transforming Weftstalker Ardent into a Pirate, allowing Malcolm, Keen-Eyed Navigator to spot the ensuing damage and shower you in Treasure tokens. Every single Treasure that arrives back on the battlefield then triggers Weftstalker Ardent all over again, creating an infinite, self-sustaining loop of damage and resources.
