Voltaic Construct + Liquimetal Coating + Deathbloom Ritualist

Voltaic Construct

Liquimetal Coating

Deathbloom Ritualist

How it works

1. Cause Deathbloom Ritualist to become an artifact using Liquimetal Coating.
2. Activate Deathbloom Ritualist by tapping it, adding at least 3.
3. Activate Voltaic Construct by paying 2, untapping Deathbloom Ritualist.
4. Repeat from step 2.

This clever loop transforms Deathbloom Ritualist into an artifact creature with the help of Liquimetal Coating, allowing it to bypass normal restrictions and tap for a massive burst of mana fueled by the fallen creatures in your graveyard. Once the ritualist yields enough mana, you can channel just a portion of it into Voltaic Construct to ready the artifact creature for another activation. By continuously untapping your newly minted artifact, you loop the process to generate an infinite supply of colored mana.
