Shao Jun + Malcolm, Keen-Eyed Navigator + Amoeboid Changeling

Shao Jun

Malcolm, Keen-Eyed Navigator

Amoeboid Changeling

How it works

1. Activate Amoeboid Changeling by tapping it, causing Magmaw to gain all creature types until end of turn.
2. Activate Shao Jun by tapping two artifacts, dealing 1 damage to each opponent.
3. Malcolm triggers, creating a Treasure for each opponent dealt damage this way.
4. Repeat.

This clever loop relies on Amoeboid Changeling's ability to fundamentally rewrite creature types, specifically granting the Pirate type to a creature that needs it—such as the implied sacrifice outlet—so it synergizes with Malcolm, Keen-Eyed Navigator. Once that typeline is established, you tap two artifacts to fuel Shao Jun's Rope Dart ability, dealing damage to each opponent and triggering Malcolm to generate a fresh batch of Treasure tokens. Because those very Treasures can be tapped alongside another artifact to pay for Shao Jun's activation, you can continuously repeat the process to burn out the table while flooding the board with infinite tapped mana sources.
