Voltaic Construct + Transmogrifying Licid + Bloom Tender

Voltaic Construct

Transmogrifying Licid

Bloom Tender

How it works

1. Activate Bloom Tender by tapping it, adding at least 3.
2. Activate Voltaic Construct by paying 2, untapping Bloom Tender.
3. Repeat

This loop relies on transforming Bloom Tender into an artifact creature using Transmogrifying Licid, allowing it to be continuously untap-fueled by Voltaic Construct. Once the Licid attaches itself, Bloom Tender gains the artifact type required for the Construct to target it, turning its color-filtering mana ability into an engine. As long as Bloom Tender is producing enough mana to cover the untap cost, you can repeat the process to generate infinite mana of any color among your permanents.
