How it works
Activate Prototype Portal by paying 0 and tapping it, creating a token copy of Mistvault Bridge.
When Mistvault Bridge enters the battlefield, Tiller Engine triggers, untapping it.
Activate the Mistvault Bridge token by tapping it, adding .
Activate Filigree Sages by paying , untapping Prototype Portal.
Repeat.
This intricate loop turns the low cost of imprinted artifacts into an engine for infinite mana and landfall triggers. With Training Grounds reducing the activation cost of Filigree Sages down to just {U}, the Sages can repeatedly untap Prototype Portal, which is primed to pump out copies of Mistvault Bridge for free. Every time a Mistvault Bridge token arrives, Tiller Engine steps in with its triggered ability to immediately untap that land, allowing you to tap it for mana before starting the loop all over again.
