Filigree Sages + Prototype Portal + Lotus Bloom + Power Artifact

Filigree Sages

Prototype Portal

Lotus Bloom

Power Artifact

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 clever loop turns Prototype Portal into a permanent-replicating engine by using Lotus Bloom—exiled via imprint and then copied repeatedly—as the ultimate fuel source, sacrificing each token for three mana to sustain the loop. The crucial secret to making this mana-positive lies in Power Artifact, whose enchantment reduces the activation cost of Prototype Portal down to just a single mana. With that cost subsidized, Filigree Sages can step in to untap the Portal using a fraction of the mana generated by the Bloom token, leaving you with an infinite supply of colored mana, mana artifacts, and token copies.
