Voltaic Construct + Biotransference + Arbor Adherent

Voltaic Construct

Biotransference

Arbor Adherent

How it works

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

Biotransference serves as the crucial foundation here by turning Arbor Adherent into an artifact creature, allowing it to benefit from Voltaic Construct's untap ability. Once Arbor Adherent is tapped to produce enough mana to cover the activation cost of Voltaic Construct—aided by its high toughness scaling—you can continuously untap the mana dork to generate an infinite loop of colored mana.
