Malcolm, Keen-Eyed Navigator + Conspiracy + Weftstalker Ardent

Malcolm, Keen-Eyed Navigator

Conspiracy

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 Conspiracy, 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 clever loop turns a simple artifact entry into an endless chain of destruction, fueled entirely by the subtle yet sweeping type-changing magic of Conspiracy. Because Conspiracy redefines every creature you own as a Pirate, Weftstalker Ardent instantly qualifies for Malcolm, Keen-Eyed Navigator's greed whenever it deals damage. The synergy locks into place as Weftstalker Ardent's own trigger causes an artifact (in this case, a Treasure) to enter, which immediately makes Weftstalker Ardent trigger all over again in an ever-escalating loop of damage and wealth.
