Voltaic Construct + Biotransference + Viridian Joiner

Voltaic Construct

Biotransference

Viridian Joiner

How it works

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

This charming loop turns Viridian Joiner into an absolute mana-producing dynamo by leaning heavily on Voltaic Construct's ability to repeatedly untap it for a modest fee. Naturally, Viridian Joiner only generates mana equal to its power, meaning it needs a little help to net a profit—which is precisely where Biotransference shines. By turning your entire team into artifact creatures, Biotransference ensures that Voltaic Construct's untap ability can legally target your newly mechanized elf, closing the loop and allowing you to churn out infinite green mana.
