This clever loop turns Battered Golem into a devastating direct-damage engine by completely transforming your board's identity with Maskwood Nexus, which grants every creature you control all creature types. Because of this sweeping type change, Titan of Eternal Fire bestows its activated ability onto the Golem, allowing it to tap and ping an opponent for one damage while also qualifying as a Pirate to satisfy Malcolm, Keen-Eyed Navigator's trigger condition. Every single time you ping, Malcolm rewards you with a newly minted Treasure token, and the moment that artifact hits the battlefield, Battered Golem's passive ability automatically untaps it so you can feed the loop with the mana you just generated.
