Malcolm, Keen-Eyed Navigator + Imagecrafter + Weftstalker Ardent

Malcolm, Keen-Eyed Navigator

Imagecrafter

Weftstalker Ardent

How it works

1. Activate Imagecrafter by tapping it, giving Weftstalker Ardent the Pirate creature type until end of turn.
2. Cause an artifact to enter the battlefield under your control.
3. Weftstalker Ardent triggers, dealing 1 damage to each opponent.
4. Malcolm triggers, as Weftstalker Ardent is a Pirate due to Imagecrafter, creating a Treasure token for each opponent dealt damage this way.
5. When the Treasure(s) enter, Weftstalker Ardent triggers that many times.
6. Resolve the first Weftstalker Ardent trigger, dealing 1 damage to each opponent.
7. Repeat from step 4.

This clever loop transforms a steady stream of artifacts into a self-sustaining engine of destruction by turning a non-traditional creature into a swashbuckler. Imagecrafter sets the stage by temporarily bestowing the Pirate creature type onto Weftstalker Ardent, allowing it to reap the rewards of piracy. Whenever an artifact enters the battlefield, Weftstalker Ardent triggers to singe your opponents, which instantly prompts Malcolm, Keen-Eyed Navigator to mint a fresh Treasure token in response to the damage dealt by your newly minted "Pirate." Because those very Treasures entering the battlefield trigger Weftstalker Ardent all over again, the resulting cascade of pings and plunder creates an endless loop of damage and mana.
