Malcolm, Keen-Eyed Navigator + Pemmin's Aura + Embraal Gear-Smasher + Amoeboid Changeling

Malcolm, Keen-Eyed Navigator

Pemmin's Aura

Embraal Gear-Smasher

Amoeboid Changeling

How it works

1. Activate Amoeboid Changeling's first ability by tapping it, causing Embraal Gear-Smasher to gain all creature types until end of turn.
2. Activate Embraal Gear-Smasher by tapping it and sacrificing an artifact, dealing 2 damage to each opponent.
3. Malcolm triggers, creating a Treasure artifact token for each opponent dealt damage by Embraal Gear-Smasher.
4. Activate a Treasure by tapping and sacrificing it, adding .
5. Activate Pemmin's Aura's first ability by paying , untapping Embraal Gear-Smasher.
6. Repeat from step 2.

This ingenious loop transforms Embraal Gear-Smasher into a devastating weapon by leveraging Amoeboid Changeling's ability to grant all creature types, making the Gear-Smasher a Pirate for Malcolm, Keen-Eyed Navigator. With Malcolm generating a Treasure token every time the Gear-Smasher deals damage to your opponents, you have an endless supply of artifact fuel and mana. Pemmin's Aura ties the whole engine together, allowing you to untap the Gear-Smasher for the cost of a single blue mana produced by sacrificing the newly minted Treasures.
