Voltaic Construct + Mycosynth Lattice + Selvala, Eager Trailblazer

Voltaic Construct

Mycosynth Lattice

Selvala, Eager Trailblazer

How it works

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

This elegant loop hinges on Mycosynth Lattice, whose static ability turns every permanent on the board into an artifact, including Selvala, Eager Trailblazer. With Selvala transformed into an artifact creature alongside her natural traits, she becomes a valid target for Voltaic Construct's ability. By tapping Selvala for a generous pile of colored mana—fueled by the varied power of creatures you control—you can easily afford the {2} activation cost to have Voltaic Construct untap her. Repeating this process yields infinite untaps for your entire artifact creature army and an unbounded supply of colored mana to fuel the rest of your strategy.
