Malcolm, Keen-Eyed Navigator + Weftstalker Ardent + Psychic Paper

Malcolm, Keen-Eyed Navigator

Weftstalker Ardent

Psychic Paper

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 Psychic Paper, 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 loop turns a simple artifact entry into an unstoppable engine of perpetual damage and infinite mana by turning Weftstalker Ardent into a fully-fledged Pirate through the disguise of Psychic Paper. Once that type adjustment is locked in, every Treasure token generated by Malcolm, Keen-Eyed Navigator upon dealing damage will enter the battlefield and immediately trigger Weftstalker Ardent all over again. The resulting cascade feeds itself endlessly, burning out your opponents while fueling an infinite supply of colored mana and artifact tokens.
