Voltaic Construct + Silverskin Armor + Deathbloom Ritualist

Voltaic Construct

Silverskin Armor

Deathbloom Ritualist

How it works

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

To pull off this infinite mana loop, Silverskin Armor plays a crucial foundational role by turning Deathbloom Ritualist into an artifact creature, allowing it to be targeted by Voltaic Construct's untap ability. Once the armor is equipped and your graveyard is stocked with at least three creature cards, tapping Deathbloom Ritualist generates enough mana to comfortably pay for Voltaic Construct's untap cost while netting a profit each cycle. By repeating this process, you easily churn out infinite colored mana and infinite untaps of your artifact creatures for any subsequent shenanigans.
