Malcolm, Keen-Eyed Navigator + Titan of Eternal Fire + Battered Golem + Mirror Entity

Malcolm, Keen-Eyed Navigator

Titan of Eternal Fire

Battered Golem

Mirror Entity

How it works

1. Activate Mirror Entity by paying 1, causing all creatures you control to have base power and toughness 1/1 and gain all creatures types until end of turn.
2. Activate Battered Golem by paying and tapping it, dealing 1 damage to an opponent.
3. Malcolm triggers, creating a Treasure artifact token.
4. When the Treasure enters the battlefield, Battered Golem triggers, untapping itself.
5. Activate the Treasure by tapping and sacrificing it, adding .
6. Repeat from step 2.

This clever loop relies on Mirror Entity's changeling-fueled ability to turn your entire board into every creature type—most importantly making Battered Golem a Human, Pirate, and artifact all at once. Because Battered Golem counts as a Human, Titan of Eternal Fire grants it the activated ability to ping an opponent for one damage by tapping itself. When that damage is dealt, Malcolm, Keen-Eyed Navigator triggers to reward your Pirate with a Treasure token. Finally, the newly created Treasure entering the battlefield triggers Battered Golem's static ability to untap itself, letting you immediately sacrifice that same Treasure for the red mana needed to keep the cycle going infinitely.
