Voltaic Construct + Faeburrow Elder + The Flesh Is Weak

Voltaic Construct

Faeburrow Elder

The Flesh Is Weak

How it works

1. Activate Faeburrow Elder by tapping it, adding at least 4.
2. Activate Voltaic Construct by paying 2, untapping Faeburrow Elder.
3. Repeat

By casting The Flesh Is Weak, its enchantment effect turns all your creatures with +1/+1 counters into artifacts in addition to their other types, transforming Faeburrow Elder into an artifact creature as long as it wears a counter. This crucial type change allows the Elder to be targeted by Voltaic Construct's untap ability. Once the conditions are right, you can tap the boosted Faeburrow Elder to generate a massive windfall of colored mana, using just a portion of those funds to activate Voltaic Construct and untap the Elder, repeating the loop infinitely for endless mana.
