Malcolm, Keen-Eyed Navigator + Leyline of Transformation + Weftstalker Ardent

Malcolm, Keen-Eyed Navigator

Leyline of Transformation

Weftstalker Ardent

How it works

1. Cause an artifact to enter the battlefield under your control.
2. Weftstalker Ardent triggers, dealing 1 damage to each opponent.
3. Malcolm triggers, as Weftstalker Ardent is a Pirate due to Leyline of Transformation, creating a Treasure token for each opponent dealt damage this way.
4. When the Treasure(s) enter, Weftstalker Ardent triggers that many times.
5. Resolve the first Weftstalker Ardent trigger, dealing 1 damage to each opponent.
6. Repeat from step 3.

This ingenious loop turns a simple artifact entry into an endless chain of destruction, fueled entirely by the static power of Leyline of Transformation to make your whole team Pirates. Once that global type-granting enchantment is in play, every Treasure token you create triggers Weftstalker Ardent's damage ability as it enters. Because Weftstalker Ardent itself counts as a Pirate, that damage directly satisfies Malcolm, Keen-Eyed Navigator's trigger condition to generate *more* Treasure tokens, feeding right back into the Ardent. The result is an infinite storm of damage and resources that can close out a Commander or Legacy game in a single fiery sequence.
