How it works

1. Activate Prototype Portal by paying 0 and tapping it, creating a token copy of Lotus Bloom.
2. Activate the Lotus Bloom token by tapping and sacrificing it, adding .
3. Activate Filigree Sages by paying , untapping Prototype Portal.
4. Repeat.

This dazzling engine uses Prototype Portal to continuously imprint and replicate Lotus Bloom, generating a ceaseless stream of free mana tokens. While the Lotus Bloom tokens sacrifice themselves for three mana at a time, Filigree Sages steps in to untap the Prototype Portal repeatedly, fueled by that very mana. To make this loop economically viable, Agatha of the Vile Cauldron steps in with her passive cost reduction, lowering the Filigree Sages' untap ability so the cycle yields a net positive surplus of infinite colored mana.
